Replace a Windows 7 computer with a Windows 10 computer. 8/10/2019; 4 minutes to read +3; In this article. Windows 10; A computer replace scenario for Windows 10 is quite similar to a computer refresh for Windows 10; however, because you are replacing a machine, you cannot store the backup on the old computer. If you have a Mac or Windows system, no matter if it is Windows 10, Windows 7, or Windows 8 and 8.1, the procedure is the same: The first step is to visit the site where you will download this emulator. Just use the button for the download. After download, the installation begins.

For better of for worse, Windows 7 is currently the most popular PC OS in the world. Even if we have never done it before, it is easy to install Windows 7 on a desktop or laptop PC. In this guide, we will go through every step, from creating a Windows 7 installation USB or DVD, all the way to logging in our new Windows installation.

How to create a Windows installation DVD or USB

If you already have a Windows 7 DVD, you can skip straight to the next section, 'Change boot order in BIOS / UEFI.'

Many of us, however, bought a PC with pre-installed Windows 7, and chances are we never got a Windows 7 DVD. Not to worry, though, since it is easy to download Windows 7 as an ISO, and then create an installation DVD or USB.

Check out our detailed guide on how to download Windows 7, legally and for free.

After we have downloaded the ISO, we can follow this guide to create a Windows Installation DVD or USB.

A Windows 7 installation USB is the best option since it will allow us to install Windows 7 faster. However, if our PC has an old BIOS that doesn't support boot from USB, the DVD is the most compatible solution.

And, speaking of the BIOS..

How to change boot order in BIOS / UEFI

A PC can boot from multiple devices, such as the hard drive, a CD/DVD-ROM, a USB thumb drive, even from the network.

The default option is usually the hard drive. To install Windows 7, we need to change the first boot device to the USB or DVD.

Changing the boot order can be tricky, though, because different motherboards often have entirely different BIOS / UEFI interfaces.

We check some of the most popular interfaces on our guide:

How to install Windows 7 from USB or DVD

So, after we have changed the boot order to our Windows 7 installation medium and boot the system, we need to press any key on the keyboard to install Windows 7.

The Digital River Windows ISOs have only a single language to install, but we can select a different time and currency format and keyboard or input methods.

On the next screen, we select 'Install Now'.. and accept the Windows License terms..

..and select 'Custom (advanced)'.


Select a hard drive or partition

There are multiple scenarios regarding the choice of the disk or partition where we will install Windows 7.

Install Windows 7 on an empty disk

On a new PC or a new disk, we just need to select the disk, which should be characterized as 'Unallocated Space'.

If we want Windows to create a single partition, we just click next.

If we have a large hard drive and want to split it into two or more partitions, we must click on 'Drive options (advanced)'..

..and then click 'New', set the size for the new partition in Megabytes (remember, 1GB=1024MB), and 'Apply'.

Windows itself, without any programs, takes about 21GB..

..but if we intend to install large programs, such as games with 50GB+ installations, we should allocate between 100GB (102400MB) and 250GB (256000MB), so we don't run out of space. The System Reserved partition is created automatically.

By clicking the rest of the unallocated space, we can create a data partition for our files.

Finally, we select the Windows partitions and click on 'Next' to install Windows 7.

Install Windows 7 on a disk that already has a Windows partition

If we had a previous Windows installation on the disk, it will show as one or more Windows partitions. Usually, the first one or two partitions - if there is a System Reserved Partition - belong to the previous installation.

Before we make any changes to the previous partitions, we need to make sure we have backed up any data on the partitions. Deleting or formatting the partitions will destroy all the files inside.

If there is data we haven't backed up, but don't have access to the previous Windows installation, we can follow this guide: Windows Won't Load? Two Ways to Rescue our Files.

With our data safe, it's best to delete the previous Windows Partitions. We just need to click on Drive options (advanced).. the partition we want to delete and click on 'Delete'.

We click OK on the warning.

We repeat until only the data partition remains, if there was one. We then click on the unallocated space and click Next to install Windows 7.

No drives are found

If we get a message that 'no drives are found', it can mean three things:

  • Windows doesn't have drivers for the particular motherboard's SATA controller
  • The hard drive isn't correctly connected to the motherboard or the power supply
  • The hard drive doesn't work

The most common scenario is that Windows needs external SATA drivers to recognize the hard drive. This will usually happen with laptops, rather than with desktop PCs.

We will find those drivers on the manufacturer's website for the laptop or the motherboard, usually as SATA or SATA AHCI.

On a second PC, we then download the drivers - usually as a .zip file - and copy all the files to a USB thumb drive.

Then, we connect the USB to the PC where we want to install Windows, click on 'Load Driver'..

..and we can either click 'OK' for Windows to search automatically for the driver or 'Browse' to point manually to the driver folder.

After that, the disks will be visible, and we can install Windows 7.

Windows cannot be installed to this disk (GPT partition style)

We will often get this error when trying to downgrade from a PC with pre-installed Windows 8 / 8.1.

The problem is that the drive has a GPT partition style, and Windows 7 cannot be installed on GPT.

To fix this issue, we must press Shift+F10 to open a command prompt window.

We type:

With Diskpart loaded, we use the list disk command to show all our hard drives, and then select disk 0 to choose the disk where we want to install Windows.

The next command will completely erase the disk, all the partitions and any data. So, make sure there isn't anything you need from that disk and everything is backed up.

To remove the GPT partition style, we type

After that we close the command prompt, click on refresh..

..and that's it. All of the partitions are gone, but the error message is also gone. We can click on drive options to create partitions, as we saw earlier, or click next to install Windows 7 on the whole disk.

Automated Windows Installation

After we selected disk or partition, Windows installation is mostly automated. It will first expand files..

..automatically reboot and continue with the installation.

Setup Windows 7

After a second automatic reboot, we just need to enter our personal information and create our user account.

First we select a username and a computer name. The computer name is the name with which our PC will show on our local network (LAN).

Typing a password is optional, but encouraged for our account safety.

We can add the product key now, but we can also add it later. Digital River Windows 7 Home Premium ISOs will work for 30 days as a full trial without a product key.

It's best to use the recommended settings for Windows update.

We select our time zone, and make sure we have the correct date and time.

If our PC is connected to our home network with Ethernet, we select Home Network to be able to exchange files with other devices through the LAN.

Windows will prepare our desktop.. 6 weeks to sick arms pdf download.

..and that's it. We have successfully installed Windows 7.

Now, the only things we have to do is install any missing drivers, which we will cover in a future guide, then install the 10 essential Windows Programs every PC should have, and any other software we need.

Most of the time, a Windows 7 clean install means to remove an existing operating system (like Windows XP, Linux, Windows 7, Windows 10, Windows 8, doesn't matter) and replace it with a fresh or 'clean' installation of Windows 7.

In other words, it's the 'erase everything and start from scratch' process for Windows 7, a procedure referred to as a 'clean install' or sometimes as a 'custom install.' It's the ultimate 'reinstall Windows 7' process.

A clean install is often the best way to solve very serious Windows 7 problems, like a virus infection you can't get rid of completely or maybe some kind of Windows issue that you can't seem to solve with normal troubleshooting.

Performing a clean install of Windows 7 is also usually a better idea than upgrading from an older version of Windows. Since a clean install is a true start over from scratch, you don't risk inheriting any buggy situations from your previous installation.

To be 100 percent clear, this is the right procedure to follow if:

  • you want to erase whatever you have and install Windows 7.
  • you want to reinstall Windows 7.
  • you want to install windows 7 on a new hard drive.

This guide is broken into a total of 34 steps and will walk you through every part of the Windows 7 clean install process. Let's get started..

The steps and screenshots shown in these steps refer specifically to Windows 7 Ultimate edition but will also serve perfectly well as a guide to reinstalling any Windows 7 edition you may have, including Windows 7 Professional or Windows 7 Home Premium.

Microsoft has changed the clean install process for every new Windows release. If you're using Windows 10, 8, Vista, etc., see How Do I Perform a Clean Installation of Windows? for links to specific instructions for your version of Windows.

Plan Your Windows 7 Clean Install

The most important thing to realize before performing a clean install of Windows 7 is that all of the information on the drive that your current operating system is installed on (probably your C: drive) will be destroyed during this process. That means that if there's anything you want to keep, you should back it up to a disc or another drive prior to beginning this process.

One quick way to back up the list of programs you have on your computer is with the CCleaner tool. It doesn't back up the actual program data but simply a list of what's installed so that you don't have to remember every program name.

You should also locate the Windows 7 product key, a 25-digit alphanumeric code unique to your copy of Windows 7. If you can't locate it, there is a fairly easy way to find the Windows 7 product key code from your existing Windows 7 installation, but this must be done before you reinstall Windows 7.

If Windows originally came preinstalled on your computer (i.e. you did not install it yourself), your product key is probably located on a sticker attached to the side, back, or bottom of your computer's case. This is the product key you should use when installing Windows 7.

When you're absolutely sure sure that everything from your computer that you want to keep is backed up, proceed to the next step. Keep in mind that once you delete all of the information from this drive (as we'll do in a future step), the action is not reversible!

Boot From the Windows 7 DVD or USB Device

To begin the Windows 7 clean install process, you'll need to boot from the Windows 7 DVD if you're using a Windows 7 DVD, or boot from a USB device if your Windows 7 installation files are located on a flash drive or other external USB drive.

See our Windows Installation FAQ if you have Windows 7 as an ISO image that you need on a flash drive or disc, or a Windows 7 DVD you need on a flash drive.

  1. Restart your computer with the Windows 7 DVD in your optical drive, or with the properly configured Windows 7 USB flash drive plugged in.
  2. Watch for a Press any key to boot from CD or DVD.. message similar to the one shown in the screenshot above. If you're booting from a flash drive, the message might be phrased differently, like Press any key to boot from external device...
  3. Press a key to force the computer to boot from the Windows 7 DVD or USB storage device. If you do not press a key, your computer will attempt to boot to the next device in the boot order, which is probably your hard drive. If this happens, chances are your current operating system will boot.

If your existing Windows installation begins to boot or you see a 'No Operating System Found' or 'NTLDR is Missing' error here instead of the screen above, the most probable reason is that your computer is not set up to boot first from the correct source. To correct this problem, you'll need to change the boot order in BIOS to list the CD/DVD/BD drive, or External Device, first.

It's perfectly fine if, instead of the screen above, the Windows 7 setup process begins automatically (see the next step). If this happens, consider this step complete and move on!

Wait for Windows 7 Installation Files to Load

You don't need to do anything at this point but wait for Windows 7 to finish loading files in preparation for the setup process.

No changes are being made to your computer at this time. Windows 7 is just temporarily 'loading files' into memory for the setup process. You'll be removing everything on your computer as part of the Windows 7 clean install in a future step.

of 34

Wait for Windows 7 Setup to Finish Loading

After the Windows 7 install files are loaded into memory, you'll see the Windows 7 splash screen, indicating that the setup process is about to begin.

You don't need to do anything at this point either.

of 34

Choose Language and Other Preferences

Choose the Language to install, Time and currency format, and Keyboard or input method that you'd like to use in your new Windows 7 installation.

of 34

Select the Install Now Button

Select Install now in the center of the screen, under the Windows 7 logo.

This will officially begin the Windows 7 clean install process.

Do not select the Repair your computer link at the bottom of the window even if you're completing this clean install of Windows 7 as part of some larger repair project for your computer.

The Repair your computer link is used to start a Windows 7 Startup Repair or perform another recovery or repair task from System Recovery Options.

If you're performing a clean install of Windows 7 as a solution to a major problem but have not yet tried a Startup Repair, do that first. It could save you the trouble of completing this clean install process.

of 34

Wait for Windows 7 Setup to Begin

No need to press any keys here–everything is automatic.

of 34

Accept the Windows 7 License Terms

The next screen that appears is a textbox containing the Windows 7 Software License.

Read through the agreement, check the I accept the license terms checkbox under the agreement text, and then select Next to confirm that you agree with the terms.

You should always read 'small print' especially when it comes to operating systems and other software. Most programs, Windows 7 included, have legally binding limits on how many computers the application can be installed on, among other limitations.

You are not breaking any laws or contracts by reinstalling Windows 7 via this clean install. As long as this particular copy of Windows 7 is only being operated on one computer, you're OK.

of 34

Choose the Type of Windows 7 Installation to Complete

In the Which type of installation do you want? window that appears next, you're offered the choice of Upgrade and Custom (advanced).

Even if you are upgrading from a previous operating system to Windows 7, I highly recommend that you do not follow the Upgrade installation. You'll get better performance with less chance of issues if you follow these clean install steps.

of 34

Show the Windows 7 Advanced Drive Options

In this screen, you'll see each partition that Windows 7 recognizes. Since a clean install involves the removal of all operating system related partitions, if they exist, we'll do this now.

If, and only if, you're installing Windows 7 on a new hard drive, which of course does not have an operating system on it to remove, you can skip directly to Step 15!

Windows 7 setup considers partition management as an advanced task, so you'll need to select the Drive options (advanced) link to make those options available.

In the next few steps, you'll delete the partitions containing the operating system you're replacing with Windows 7, be it Windows Vista, Windows XP, a previous installation of Windows 7, etc.

of 34

Delete the Partition Windows Is Installed On

Now that all available drive options are listed, you can delete any operating system related partitions from your existing hard drive(s).

Before continuing, please be aware that deleting a partition will permanently erase all data from that drive. By all data I mean the operating system that's installed, all programs, all data saved by those programs, all music, all video, all documents, etc. that might be on that particular drive.

Highlight the partition you want to delete and then select the Delete link.

Your list of partitions may differ considerably from mine shown above. On my computer, I am performing a clean install of Windows 7 on a computer with a small 30 GB hard drive that has previously had Windows 7 installed.

If you have multiple hard drives and/or multiple partitions on those drive(s), take great care in confirming that you're deleting the correct partition(s). Many people, for example, have second hard drives or partitions that act as backup drives. That's certainly not a drive you want to be deleting.

of 34

Confirm the Partition Deletion

After deleting the partition, Windows 7 setup will prompt you to confirm the deletion.

The message says 'The partition might contain recovery files, system files, or important software from your computer manufacturer. If you delete this partition, any data stored on it will be lost.'

As I spelled out in the last step, please be aware that all the data stored on that drive will be lost. If you have not backed up everything you want to keep, select Cancel, end the Windows 7 clean install process, restart your computer to boot back into whatever operating system you have installed, and back up everything you want to keep.

To be clear: This is the point of no return! There's no reason to be scared, I just want it to be very clear that you can't undo the deletion of the drive you selected after you choose this OK button.

of 34

Delete Other Operating System Related Partitions

If there are any other partitions that need to be deleted, you can do so at this time.

For example, the Windows 7 installation I had on my PC previously created this special 100 MB (very small) partition to store system data in. This is most definitely related to the operating system that I'm trying to completely remove from my computer, so I'll delete this as well.

Highlight the partition and select the Delete link.

As you can see, the partition we deleted in the last step is gone. It may appear like it's still there but if you look closely, you'll see that that same 29.9 GB space is now described as Unallocated Space, not as a partition.

of 34

Confirm Additional Partition Deletions

Just as in Step 12, Windows 7 setup will prompt you to confirm the deletion of this partition.

Just as before, please be aware that all the data stored on this particular drive will be lost.

of 34

Choose a Physical Location to Install Windows 7 On

As you can now see, all the space on the installed hard drive is unallocated. No partitions exist on this computer.

The number of partitions displayed and whether those partitions are unallocated portions of a hard drive, previously partitioned spaces, or previously formatted and blank partitions, will depend on your specific system and which partitions you deleted in the last several steps.

If you're installing Windows 7 on a computer with a single hard drive on which you've just deleted all the partitions from, your screen should look like the one above, aside from your hard drive being a different size.

Choose the appropriate unallocated space to install Windows 7 on and then select Next.

You do not need to manually create a new partition nor are you required to manually format a new partition. Windows 7 Setup will do this automatically.

of 34

Wait While Windows 7 Is Installed

Windows 7 Setup will now install a clean copy of Windows 7 to the location you chose in the previous step. You don't need to do anything here but wait.

This is the most time consuming of any of the 34 steps. Depending on the speed of your computer, this process could take anywhere from 5 to 30 minutes.

of 34

Restart Your Computer

Now that the Windows 7 clean install process is nearly complete, you need to restart your computer.

If you do nothing, your computer will reset automatically after 10 seconds or so. If you'd rather not wait, you can select Restart now at the bottom of the Windows needs to restart to continue screen.

of 34

Wait for Windows 7 Setup to Begin Again

You don't need to do anything here. There are a few more automatic Windows 7 setup steps to come.

of 34

Wait for Windows 7 Setup to Update Registry Settings

Windows 7 Setup is now updating registry settings in preparation for the final stages of the operating system clean install.

of 34

Wait for Windows 7 Setup to Start Services

Wait while Windows 7 Setup starts various necessary services.

This starting of services will occur during every Windows 7 boot as well but you won't see it like this again. Services start in the background during a normal Windows 7 startup.

of 34

Wait for Windows 7 Setup to Complete

This last Windows 7 Setup screen says 'Completing installation' and may take several minutes. All you need to do is wait–everything is automatic.

If the Windows 7 Setup process is complete, why are we only on step 21 of 34?

The remainder of the steps in this clean install process include several easy but important configurations that need to take place before you can use Windows 7.

of 34

Wait for Your PC to Automatically Restart

Wait while the Windows 7 setup process automatically restarts your computer.

Do not restart your computer manually at this point. Windows 7 Setup will restart your PC for you. If you interrupt the setup process by restarting manually, the clean install process may fail. You may then need to start the Windows 7 setup over again from the beginning.

Wait for Windows 7 to Start

Install Windows 7 On New Windows 10 Computer

No user intervention is required here.

of 34

Wait for Windows 7 to Prepare Your PC for First Use

Windows 7 Setup is now preparing your computer for 'first use.'

Windows 7 is now loading drivers, checking to make sure everything has been setup properly, removing temporary files, etc.

Remember, this clean install of Windows 7 has completely removed your old operating system. Windows 7 is being installed and configured just as it would on a brand new computer.

of 34

Wait for Windows 7 to Check Your PC's Video Performance

Wait while Windows 7 checks the video performance of your computer.

Windows 7 needs to know how well your video card and related hardware works so it can properly adjust performance options for your computer.

For example, if your video system is too slow, Windows 7 may disable features like Aero Peek, translucent windows, and other graphically intense features of the operating system.

of 34

Choose a User Name and a Computer Name

Windows 7 needs to know what user name you'd like to use and how you'd like your computer to be identified on your local network.

In the Type a user name (for example, John): text box, enter your name. You can enter a single name, your first and last name, or any other identifiable text you like. This is the name you'll be identified by in Windows 7.

You're more than welcome to use the same user name that you used in your old operating system installation.

In the Type a computer name: text box, enter the name you'd like your computer to have when being viewed by other computers on your network.

If it makes sense in your specific situation, I recommend using the same computer name you used in the operating system installation you've deleted as part of this clean install, especially if any other computers on your network connect to resources on your PC.

Otherwise, a good computer name might be Office-PC, Windows-7-Test-PC, Bob-Dell, etc. You get the idea. Anything identifiable that makes sense to you will work.

Select Next when you're done entering both the user name and computer name.

Planning on having more than one user on your computer? Don't worry–you can set up more users inside Windows 7 later.

of 34

Choose a Password to Access Windows 7

Microsoft recommends that you choose a password that will be required when starting Windows 7 before access to your user account will be allowed.

Don't treat this as a recommendation–consider it a requirement.

In the Type a password (recommended): text box, enter a complicated but easy-for-YOU-to-remember password. Retype the same password in the Retype your password: text box.

Type a hint to give yourself in the Type a password hint (required): text box. This hint will display if you enter the wrong password when logging on to Windows 7.

As you can see in the example above, the hint I entered was What is my favorite food?. The password I entered (which you can't see above) was applesauce.

Feel free to use the same password as you used in the operating system you've just removed from your computer as part of this Windows 7 clean install. However, this is as good a time as any to choose a stronger password than you might have used before.

of 34

Enter the Windows 7 Product Key

Enter the product key that came with your retail purchase or legal download of Windows 7. If Windows 7 came as part of your complete computer system, enter the product key you were given as part of that purchase.

If Windows originally came preinstalled on your computer, your product key is probably located on a sticker attached to the side, back, or bottom of your computer's case.

You may be able to avoid entering a product key at this point but you will eventually need to do so in order to continue using Windows 7. I highly advise that you enter your product key here and choose to Automatically activate Windows when I'm online.

How To Install Windows 7 On A Windows 10 Computer Dual Boot

of 34

Choose a Windows Update Option

On this Help protect your computer and improve Windows automatically screen, Windows 7 is asking you to choose how you want to automatically install updates from Microsoft's Windows Update service.

I recommend that you choose Install important updates only. This option is the safest because it restricts Windows 7 from doing anything with your data or to your computer automatically except when important security and stability updates are available.

You are more than welcome to choose Use recommended settings but I do not recommend that you choose Ask me later.

These settings can easily be changed within Windows 7 after you're done stepping through these configuration questions.

of 34

Choose the Correct Time Zone, Date, and Time

On the Review your time and date settings screen, choose the correct Time zone, Date, and Time.

The time and date is likely already correct but be sure to verify the time zone and change if necessary.

If your area observes Daylight Saving Time be sure to check that box here.

If the date and/or time of Daylight Saving Time changes, Microsoft will issue an update via Windows Update to change the automatic time change, so don't avoid checking this box assuming that DST changes won't occur correctly.

of 34

Choose a Network Location

In the Select your computer's current location window you see now, Windows 7 is asking where your computer is located at so it can set up the proper network security–tighter security for public areas and lighter for private ones like home and work.

Choose Home network or Work network if that applies to you. Most of you reading this will choose Home network.

Choose Public network if you use a mobile computer and you connect to the internet or other computers away from home. Also, be sure to choose Public network if you access the internet via a mobile broadband network–no matter if you're at home or not.

of 34

Wait for Windows 7 to Connect to the Network

Windows 7 is now connecting your computer to the network.

You don't need to do anything here. Everything is automatic.

If Windows 7 detects another computer on your network running Windows 7 that also has a homegroup set up, you will be prompted to choose what kinds of files you'd like to share on that homegroup and for the homegroup password. You can enter this information or Skip the setup entirely.

I do not show this additional screen in this guide.

of 34

Wait for Windows 7 to Prepare the Desktop

Windows 7 will now put all the 'finishing touches' on your clean installation like adding icons to the desktop, prepare the start menu, etc.

You don't need to do anything here. All of these changes are done automatically in the background.

of 34

Your Windows 7 Clean Install Is Complete!

This completes the final step of your clean install of Windows 7. Congratulations!

If you chose not to enable automatic updates (Step 29), then the first step after installing Windows 7 is to visit Windows Update and install all the important service packs and patches that have been issued since the version of Windows 7 on your DVD was released.

In other words, any service packs and patches installed on your old operating system are obviously no longer installed.

If you did enable automatic updates, Windows 7 will prompt you about any important updates needed.
