Boot Issues Windows 11
Boot Issues Windows 11
Hi everyone. I'm using Windows 11 Pro.
I attempted to install Linux on a thumb drive but the installer corrupted my boot drive. When I don't do anything during startup, it boots into Grub.
In the boot options menu, I see several choices:
ubuntu
UEFI : Built-in EFI Shell
Samsung SSD 970 EVO 500GB : PART 0 : Boot Drive
Picking the first option boots to Grub.
Selecting the second leads to the shell.
Going to fs1:\EFI\Microsoft\Boot> and running bootmgfw.efi gets me back to Windows.
The third option shows a warning: "Reboot and Select proper Boot device or Insert Boot Media..."
I need the machine to boot directly to Windows and eliminate the Ubuntu installation.
Any advice?
Hello there, new member! I plan to rebuild the bootable USB for Windows 11 and then reinstall the operating system from scratch.
The simplest method is to modify the BIOS settings
Swap GRUB for Windows Boot Manager
In this guide, we explain how to substitute GRUB with Windows Boot Manager. A lightweight program named Windows Boot Manager (BOOTMGR) can be used.

The Windows Boot Manager isn't showing up in my UEFI boot devices. However, it's present in the filesystem if I boot into the UEFI Shell and go there. It seems it might have been affected by the system's database when the options were displayed.
I really wish Ubuntu hadn't altered my drive while I was just trying to create a bootable Linux thumb drive. This is really frustrating.
I'm very worried about causing more problems.
I wonder if resetting the CMOS would revert it to the defaults. EFI is merely a boot choice, though it isn't the standard one. It appears Ubuntu employs the EFI Shell, so be gentle with it. I haven't used it myself, but the video clarifies it well. You don't need to modify the BIOS. A CMOS reset should accomplish that.
Why?! Linux is already available on USB, just like with your usual downloads—you simply need to "burn" the USB drive.

Start with the free (community) version of easybcd, go to the bcd deployment tab, and write or install a new BCD file on the main disk.
You might consider a BCD repair, but since you only have a basic BCD file to load into the main OS, creating a fresh one will be much simpler.
