No Operating System found on my hard disk after installing GNOME

After installation try running:

  1. manjaro-chroot -a
  2. update-grub

Does it find the Installation?

grub-probe: error: cannot find a GRUB drive for /dev/sdb1.  Check your device.map.

I think /dev/sdb1 is the install drive

Type 2 and enter.

Correct :+1:

I didn’t reinstall it again.

So here is everything correct.

It has to do with your BIOS then.

Do I have to go into my BIOS setup?

Yes, guess it is the boot order then… idk.

Welp, I reset my BIOS settings to default and that did nothing AFAIK since the issue is still there.

Just a thought, but maybe your BIOS need a primary boot partition? Your root partition is a logical one now, which contains /boot…

Also please post your system:
