i prefer to switch between different operating systems at times on the same machine, not just using the same drive. I don’t like dual booting, so I always use separate drives. Right now I have Windows 10, and I wanted to test Windows 8.1 on my hardware to check compatibility. It didn’t work, so I wiped the drive, cleared it for games, and reformatted it using CMD commands. After that, I formatted it again, but even though it’s gone, I can’t start Windows without being prompted to pick an OS—either Windows 8 or 10. It keeps asking which one to use. I tried MSConfig, deleted the boot volume, changed the boot order, and applied settings, but it still pops up with a choice. I repeated the process several times, ran an upgrade tool for Windows 10, and even pressed F9 twice to fix it, though I’m not sure what’s causing the issue. I don’t want to reinstall Windows, I’m comfortable with my current key, and it still works. What should I do?
You've only deleted the contents of Windows 8 Since Win10 can read the presence of Win8 and this is a GPT drive, I assume that Win8's bootloader is still in the EFI partition of the boot drive I don't know how to get it removed but this might be it (perhaps using cmd will force delete it): https://winaero.com/delete-boot-menu-ent...indows-10/
Open msconfig, select Windows 8.1, press delete, then confirm. The boot option is saved to the boot configuration (BCD) in the Windows 11 boot partition. Clearing all Windows 8 partitions will prevent Windows 11 from recognizing this setting and retains the original boot entry. For more information about BCD entries, run the command BCDEDIT in cmd.exe with admin privileges.
