I have 4 different OSs on 4 SSDs, sda thru sdd. When I run
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
I get:
generating grub configuration file …
Found Ubuntu 20.04 LTS (20.04) on /dev/sda1
Found SUSE Linux Enterprise Desktop 15 SP1 on /dev/sdb1
Found SUSE Linux Enterprise Desktop 15 SP1 on /dev/sdb1
Found openSUSE Leap 15.1 on /dev/sdd3
Found openSUSE Leap 15.1 on /dev/sdd3
Note that it doesn’t list fedora-32 on sdc.
Then I run:
sudo grub2-install /dev/sda
and get
Installing for i386-pc platform.
Installation finished. No error reported.
When I boot the choices are fedora-32 or Ubuntu, but not the SUSE OSs.
How can I add the SUSE OSs as boot choices?
