Are you installing in BIOS or in UEFI mode?
I don't know, to be honest. And I'm some 25 km's away from the system in question, so it's not easy to tell right now.
There are commands that could tell you this, but I'm not sure which.
You could try "efibootmgr". What I do not know is what it prints in BIOS mode.
I'm confused because this message happens when using BIOS mode, but I see later that you have the /boot/efi partiton.
If you are installing in BIOS mode, then you need that BIOS boot partition, or if not, make sure that:
MBR contains generic boot code System boots from root partition Root partition is flagged bootable.
Therefore, AND not knowing what the installer wanted, I decided to continue.
But this time the installation itself went smoothly, but left me with an unbootable system: there is no valid partition found to boot from.
The partitions on the disk are:
/dev/sda1 4.00 GiB Swap on Swap /dev/sda2 50.00 GiB BtrFS on / /dev/sda3 0.86TiB XFS on /home /dev/sda4 1.00 GiB FAT on /boot/efi
sda4 is too big, 500M is enough. Why you have it is a mystery, anyway.
I wouldn't know either, I got the system presented as is. Should I delete it?
No. You did not create it now?
Why did the system boot on 42.3, and refuses it to boot from 15.2?
We don't know how your 42.3 was installed.
Here again, I don't really know. Must be way back.
"bootinfoscript" could have told you that. download from:
More important, what can I do to make the system boot? Preferably without touching /home...
First find out: BIOS or UEFI?
To find that out, I have to boot with a live "CD" I suppose? KDE or Rescue?
No, you have to get to the BIOS config page.
When you boot the installation DVD, the display is slightly different, too. It could be nice if it displayed "BIOS/UEFI mode" too.
