Grub is missing Kubuntu?

30_os-prober

Does it make a difference if it is called 30_os-prober_proxy?

if zorin or bazzite still don't show , there's further steps then

Zorin shows in the konsole, Bazzite doesn't.

I have no idea what the "_proxy" version is about. I use Kubuntu and KDEneon and that entry does not exist for us. You should probably ask in a Zorin or Bazzite forum.

ok now add bazzite manually to grub: run

sudo find /boot/efi/EFI -name "*.efi"

you should see either /boot/efi/EFI/bazzite/grubx64.efi or /boot/efi/EFI/fedora/grubx64.efi
make note which one
now add custom grub entry with

sudo nano /etc/grub.d/40_custom

and add this at the bottom
menuentry "Bazzite" {
insmod part_gpt
insmod fat
search --file --set=root /EFI/bazzite/grubx64.efi
chainloader /EFI/bazzite/grubx64.efi
}
(if the folder was fedora,replace bazzite with fedora)
save and exit (ctrl+O - enter - ctrl+X)
then again

sudo update-grub

no errors should appear

reboot
