CentOS /boot is on separated xfs partition.
Legacy BIOS.
Any idea please ?
After booting 15.1, in
YaST > Boot Loader > Bootloader Options
is the checkbox “Probe Foreign OS” checked?
Note all OS’s must boot using the same method or they won’t see one another
It was grayed so I checked it.
kexec-tools was then installed but CentOS is still missing in grub menu.
Can you please write something more about method of booting ?
Wrong. At least Linux does not care (you can boot the same installation both using BIOS and EFI).
Missing information, here. You might want to explain why kexec-tools isn’t installed. Seems to me it is usually installed by default. Looks to me like you’ve been doing some fiddling around.
Run as root
NOW=$(date +%s)
os-prober
journalctl --no-pager --since=@$NOW
and post full output.
It’s probably result of failed distribution upgrade. But problem with missing CentOS had appeared much earlier.
There are two main ways to setup booting MBR(legacy) and EFI. If you mix modes the installer may not see any OS in a different mode thus it does not get added to Grub. If you installed Centos in legacy mode and openSUSE in .EFI the legacy mode OS may not be seen by the setup tools and not be added to the grub menu.
In general you need to boot the installer in the mode you want to use to boot the OS and for simplicity all OS’s should use the same boot method.
Stop spreading absolute nonsense.
CentOS boot partition is on /dev/sda6

All OS’s are installed in legacy mode.
It is not nonsense Multi boot using mixed boot methods is not automatic and requires manual intervention even if it is multi-Linux Best practice is don’t mix boot methods you you will have to fix things.
.
With all in legacy mode it should just work unless you have odd setups like encryption or something else somewhere and setting include foreign .in Yast boot loader should bring the other OS into the grub menu.
os-prober should show an other OS visable
I’ll have to agree with arvidjaar on this one.
With linux, it does not matter. I have had no difficulty installing for legacy booting, then booting with EFI (from the menu of another linux install).
You can’t mix with Windows, but you can with linux.
It looks as if os-prober is not seeing your CentOS system. And that probably means that it is broken in some way.
CentOS /boot partition is not encrypted.
Yes it does.
When I copy part of grub.cfg from CentOS into grub.cfg from openSUSE, it is visible and working.
