[TahsinAyman]

i have windows installed with on legacy boot. bcs without legacy boot it keeps showing error saying "windows cannot update computer's boot configuration" anyways after that i installed windows with MBR partition and then it installed correctly. point to be noted i had to reinstall windows for some reason. after that i am need of secure boot bcs i want to play valorant. so i converted my disk to gpt and booted with uefi boot enabled (secure boot disabled) it booted correctly. but after that i enabled secure boot it returns with "boot device failed.". help me boot windows with secure boot enabled.

OS: windows 11
product serial number: [personal info removed]

The only suggestion I can offer would be to enable secure boot and clean install W11 by making a bootable USB installation flash drive with the media creation tool from the link below (2nd option).

Download Windows 11

Boot the installation media from the (U)EFI flash drive, not the legacy one.

See if it works that way.

I tried but it responded with "Windows failed to install". it completed 100% but then it says failed. earlier i tried downloading windows 10 using their installation media on uefi enabled, but it always completed 100% and then it says "Windows cannot update computer's boot configuration". i use arch btw (dual booted) (idk if this info is usefull) but please help

Unfortunately, I wouldn't know what the problem could be but the Linux OS you have installed may be causing a problem with the installation.

The only final suggestion I can offer would be to clean the disk during the Windows installation, so it removes everything on the drive including Linux.

Boot from the installation media and when you get to the part of the installation that asks, 'Where do you want to install Windows,' run the diskpart utility to clean the disk.

1. Press Shift+F10 from inside Windows Setup screen to open a command prompt window.
2. Type diskpart and press the Enter key.
3. Type list disk to find your disk number.
4. Type select disk (e.g., select disk0) to choose the disk you want to format.
5. Finally, type clean to wipe the disk completely.
6. Exit diskpart and install Windows.

Sorry, I won't be able to help you.

You'll have to leave Windows in legacy mode and find another video game to play that you will enjoy.
