I just installed Bazzite over my old Ubuntu system, but the Ubuntu option still shows up in my boot manager and GRUB menu. I attempted to remove it using the command "sudo efibootmgr -b 0002 -B", and it seemed to work, but after restarting, the Ubuntu option reappears. Any ideas on how to properly remove it?

If `sudo update-grub` isn't working for you, maybe there's an issue with your GRUB configuration. You can also check your `/etc/default/grub` settings to make sure everything looks right. Sometimes a quick update there can solve boot issues.

Have you tried running `sudo update-grub` after you remove the entry? That can sometimes refresh the boot menu. Let me know how that goes!
