with yast I just updated all packages for which a newer version existed.
I asked for a reboot due to kernel update.
after that it doesn’t boot any longer.
I can select the system with grub, but this immediately results in a screen with the following message (numers omitted):
kernel panic - not syncing: VFS: Unable to mount root fs on unknown block(0,0)
Pid:1, comm… (as above)
the rescue system on the disk can be booted and the partition can be mounted and accessed.
fsck says the partition is ok.
a parallell Win on the disk can be booted.
-> can that be repaired (how?), or do I have to perform a new install?
Does your rescue system offer a facility to repair the installed system i.e. replace packages, or even run a system upgrade depending on whether “disk” refers to DVD installation media?
I made the kernel update this morning on my 12.2 system (using Apper) with no issue, except I had to run “update-bootloader --refresh” from my 12.3 system before it would reboot with Grub2. That’s only because I multiboot several openSUSE releases, and it shouldn’t affect your situation. If I hadn’t used Apper, I would have used YaST Online Update (YOU) to make the kernel update. Did you use YOU, if not then perhaps you should (next time)?
PS. Just seen your correction post after writing, so take that into account when reading this.
