How to install Windows 11 on Windows 7 without losing data

Since Microsoft has stopped providing upgrade services for Windows 7, it is not possible to upgrade directly from Check for updates. But it still supports upgrading from Windows 10 to Windows 11. So we need to upgrade Windows 7 to Windows 10 first, and then upgrade Windows 10 to Windows 11.

Here is how to upgrade from Windows 7 to Windows 10:

To ensure safety, you’d better back up your data. Due to the differences between Windows 10 and Windows 7, not all applications will be retained.

Create Windows 10 installation media from Microsoft, and launch it.

● Choose “Upgrade this PC now”.

● Once the upgrade is complete, you should receive a digital license for Windows 10, which can be found under Settings > Update & Security > Activation.

Before upgrading to Windows 11, your PC should meet the system requirement for Windows 11. Of these, most notably, Windows 11 needs to be booted in UEFI boot mode, which means that our system disk must be a GPT disk. If your system disk is an MBR disk, you must convert MBR to GPT, and then change the boot mode from the BIOS to UEFI.

Step 1. Convert MBR disk to GPT disk without data loss

I recommend using AOMEI Partition Assistant Professional to convert MBR to GPT, because it will not lose any data. Whether you are using Windows 10/8.1/8/7/Vista or Windows XP, it is compatible. Now, please download the demo version to see how to convert system disk from MBR to GPT.

2. Click “OK” to confirm your operation.

3. Click “Apply” to commit the pending operation.

Step 2. Change BIOS to UEFI

Now, you need to change BIOS to UEFI:

1. After restarting the computer, When a picture appears on the computer screen, enter the BIOS according to the key prompted at the bottom of the screen (keys vary from PC to PC).

2. Use the arrow keys to select UEFI/BIOS Boot Mode in the Boot column, and then change Legacy to UEFI. Then saving and exit.

After completing these operations, restart the computer. Now your Windows 10 has been booted from UEFI, and the system disk is also a GPT disk.

Step 3. Upgrade from Windows 10 to Windows 11

Finally, you just need to go to Settings> Update and Security> Check for updates. If available, you will see Windows 11 feature updates. Click Download and Install to complete.

Conclusion

This is the whole process of how to install Windows 11 on Windows 7. If you don’t want to perform a clean install, you can also upgrade from Windows 7 to Windows 10 first, and then upgrade to Windows 11. With the help of AOMEI Partition Assistant Professional, converting MBR to GPT will no longer be a problem.
