Hi guys, I am using Windows 11 Pro. When I tried to put Linux on a thumb drive, the installer accidentally messed up my hard drive. Now it boots to Grub instead of Windows. If I just sit there without touching anything when starting up, it shows this list: ubuntu UEFI : Built-in EFI Shell Samsung SSD 970 EVO 500GB : PART 0 : Boot Drive Choosing the first option gets me back to Grub. Choosing the second option opens a shell. If I go to fs1:\EFI\Microsoft\Boot> and run bootmgfw.efi, it boots back to Windows. The third option says: "Reboot and Select proper Boot device or Insert Boot Media..." Can I fix this? I want my computer to start straight into Windows and get rid of that Linux stuff. Thanks!

Welcome to the forum! If you are new here, I want to help create a bootable USB disk with Windows 11 so we can start fresh with a clean install.

The easiest way is to switch your BIOS settings so that it uses the Windows Boot Manager instead of GRUB. Right now, in this article, we show you how to change GRUB to use the Windows Boot Manager. A small piece of software called Windows Boot Manager (BOOTMGR), which is www.compsmag.com
