Grub is missing Kubuntu?

[Wobbelblob]

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.

[oshunluvr]

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.

[die.boer]

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

The problem is that I see that version while being in Kubuntu. I haven't done any steps in Bazzite...

you should see either

Well, I am seeing neither. I see 8 entries, 3 of them being /ubuntu/, 2 being /BOOT/ and 3 being /kubuntu/

[die.boer]

please post output of terminal of this

sudo efibootmgr -v

[die.boer]

sudo nano /etc/grub.d/40_custom

delete the previous entry you made , and add this instead
menuentry "Bazzite" {
insmod part_gpt
insmod fat
search --no-floppy --set=root --file /EFI/FEDORA/SHIMX64.EFI
chainloader /EFI/FEDORA/SHIMX64.EFI
}
save and exit
rebuild grub with

sudo update-grub

then change boot order with

sudo efibootmgr -o 0003,0004,0000,0006,0001,0005

reboot

PS: if all that works ,we can clean up duplicate EFI entries (you currently have two Fedora and two Ubuntu entries)

[Wobbelblob]

sudo update-grub

After adding said code, that produces the following result with a syntax error:

​

[die.boer]

recheck the grub custom file you added

sudo nano /etc/grub.d/40_custom

make sure everything is exactly like this
menuentry "Bazzite" {
insmod part_gpt
insmod fat
search --no-floppy --file --set=root /EFI/FEDORA/SHIMX64.EFI
chainloader /EFI/FEDORA/SHIMX64.EFI
}

save and exit - then

sudo update-grub

and reboot

PS: after the last } sign,press enter,so there's a empty line
if it still doesn't work ,try replacing that entry with
menuentry "Bazzite" {
insmod part_gpt
insmod fat
chainloader /EFI/FEDORA/SHIMX64.EFI
}

save and exit - then

sudo update-grub

and reboot

[Wobbelblob]

Both produce a syntax error, though the error line is 284 and 283 respectively.

#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.
menuentry "Bazzite" {
insmod part_gpt
insmod fat
chainloader /EFI/FEDORA/SHIMX64.EFI
}​h
 


​}​

​

Is what is written in the file you mentioned. Though I do not know where either the "h" or the second } is coming from, that is only visible in the texteditor and neither in the konsole or if I open the script in a texteditor.

[die.boer]

that h and } shouldnt be there

[Wobbelblob]

I know. But as I said, in the script file and the konsole neither are shown. It is only there when I copy it from the konsole to a text editor to remove the formatting.

[die.boer]

my suggestion now would be to open the file again

sudo nano /etc/grub.d/40_custom

, delete everything after the header, and retype it manually so the file looks exactly like this:
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.

menuentry "Bazzite" {
insmod part_gpt
insmod fat
chainloader /EFI/FEDORA/SHIMX64.EFI
}

after you type the last } , press enter once

save and exit
then again

sudo update-grub

hopefully no errors now
reboot

[Wobbelblob]

It worked! I have no idea why that error apparently happend, but now it not only run through without error, Bazzite also now shows in the GRUB entry. Thanks for the patience and the help!

Glad that is sorted
