    How Do I Downgrade To Windows 7?


    Hi Eight Forums,
    I recently got an Acer Aspire E1-571-6442 and I have been using Windows 8 for a bit to try it out. I have decided to downgrade to Windows 7 Home Premium x64, but whenever I load the setup I get this error:
    Windows cannot be installed to this disk. The selected disk is of the GPT partition style. I have tried going into Legacy BIOS mode to disable secure boot, but that didn't work either. How can this be fixed?

    No worries. You just didn't open an "elevated" (run as administrator) PowerShell from step 1. Click on the link in step 1 for more details to help.

    I would suggest keeping windows 8 and just install classic shell or Start8. Classic shell is free and Start8 is free to try for 30 days then cost $5. This way you get the look and feel of 7 but with all the benefits of 8.

    Welcome to Classic Shell

    Windows 8 start menu returns with Start8 from Stardock!

    My BIOS is in UEFI mode but secure boot is still enabled. Should I change it to legacy BIOS?

    You would need to continue at step 3 since secure boot is enabled.

    If you wanted to install Windows 7 with UEFI, then you do not want to change it to legacy BIOS.

    Legacy is without UEFI.

    The video below can better help with the differences. Since your motherboard supports UEFI, it would be better to install with UEFI to take advantage of it.
