I've got a bit of a quirky situation here. A few months back, I installed ZorinOS on my desktop. Things went haywire with my Windows 11 setup, leading me to reinstall it on a different SSD instead of wiping my old Windows boot drive. After salvaging what I could from the corrupted install, I wiped the partition that had Zorin (it was in a small partition). However, now I see Zorin listed as a boot option in my BIOS, even though I've formatted that drive! It's not causing any immediate issues since it automatically boots into Windows, but with plans to install CachyOS soon, that old Zorin option is a bit unsettling. I'm curious about how to remove it from the BIOS and whether it's harmful if I accidentally try to boot into Zorin when it's not there. Thanks for any help!

You can definitely clear out those old boot options in your BIOS. Usually, they keep those entries stored even after you wipe the drive. If it bothers you, just go into your BIOS settings and find the option to delete or manage boot entries. It should be pretty straightforward!
Yeah, just look for 'Boot Options' or 'Boot Order' in your BIOS menu, and you should find the option to delete old entries.
It sounds like you might still have some remnants of GRUB that need cleaning up. Those entries can linger even after you delete the OS. You can remove them by reconfiguring GRUB to reflect your current OS setup, or if you're done with dual-booting, just delete the entry. It won't harm your system to try to boot into a missing OS; like others said, you'll just see an error and boot into your existing system.
Glad to hear it's just an error if I try to boot it! I want to learn more about GRUB configuration; any tips?
You're right, seeing old boot options can be annoying, but it's usually not a big deal. Those EFI boot entries are stored in the NVRAM, and formatting the drive doesn’t wipe them out. If you try to boot into Zorin, it’s just going to throw an error message and then go back to the boot menu, so there's no risk of bricking your system or anything. If you want a fresh start, though, reinitializing GRUB or removing that entry is a good way to go.
Phew, thanks for the clarification! I was really nervous about messing something up if I accidentally tried to boot it.
That's exactly what I was wondering! Do you know how to do it on a Gigabyte board?
