Hello everyone, I'm dealing with a dual-boot setup. I have two SSDs—one running Ubuntu and the other Windows. After a BIOS update on my motherboard at a repair shop, the Windows SSD appears but isn't listed as a boot option anymore. I can switch it to legacy mode, but I need UEFI enabled for secure boot, which isn't possible there. I think formatting the Windows drive and reinstalling in UEFI would fix it. Should I create a fresh Windows 11 OS and format it in the correct partition type during installation, or should I work with Ubuntu? Thanks!

I think it's possible to convert from MBR to GPT without reinstalling Windows or reformatting. The Windows 11 installation process might offer the chance to set it up properly. Regarding its effect on your dual boot or bootloader, I'm not sure. If the issue is due to CSM being turned off and the drive still using MBR formatting, that could be the cause.

It seems the update cleared the Secure Boot credentials.

I believe it might be GPT. However, I'm certain to verify on Ubuntu. If it's GPT, I'll understand the problem. If it's GPT, I assume the OS image was made for legacy mode instead of the new UEFI setup.

For legacy boot only, switch to Windows and use mbr2gpt to transform your drive to GPT. Once done, turn off legacy boot and activate secure boot. (Windows doesn’t require reinstall and you won’t lose any data during the conversion.)

Similar setup but for an Ubuntu system. Disk type is DOS, so it isn’t recognized and urfi can’t boot, which is why it’s not listed. You’ll need to figure out how to convert from DOS to Ubuntu.

Your message seems unclear. Did you mean to ask about booting to Windows with secure boot and whether Linux uses DOS or different file systems like ext4 or Btrfs? There’s no need to convert Ubuntu if you’re already using it.

This would fix the problem, though you could potentially recover the installation by reaching out for help

I think my reasoning might have been a little wrong. Since I didn’t have another Windows machine and I wasn’t worried about losing data, I created a bootable USB from my Ubuntu drive with Windows 11, reinstalled it using GPT, and now everything is functioning properly. My 2017 PC is still running smoothly at 60 FPS in Battlefield.
