    This disk has been installed with, I think, openSuse 12.1 or even older, on a motherboard what for as far as I know did not support UEFI yet.
    The motherboard died, and got replaced with a modern Gigabyte board, and the OS upgraded with zypper dup, version after version to 13.2.

    So the disk is not EFI, the installer wants EFI if the BIOS is set to "EFI and Legacy", and does not see the disk in it's non-EFI partitioning. BIOS refuses to see the installer stick if changed to "Legacy only". BIOS refuses in either mode to boot from the disk (but that was the cause to start this thread...)

    Hi
    I would wipe the disk, set as gpt, configure the partitions and re-install as efi (but that's just me). A little bit of work in rescue mode, but doesn't take long (can provide details on what I do).

    Else set the bootflag to sda2 via fdisk and re-install the mbr code (wonder if it was set to install boot code into sda2?) and leave at legacy and see if it boots.

    If a new mother board it is probably UEFI and not BIOS to select legacy boot you have to press a hot key at boot which one depends on the UEFI installed sometimes F12 or F10 or ??? best to find a manual for the mother board in question or it may show on the boot splash screen.

    You now seem to now have a mix of GPT and DOS partitioning that may cause some confusion

    If you boot in the wrong mode the installer may not pick up the installed OS for a upgrade.

    I agree with malcolmlewis and say the easiest way over all is to backup the home wipe the drive and do a new install

    Hi all,

    I've indeed decided to do a new install from Leap 42.1, wipe the disk from within the installation program and partition/format it conform EFI-standards.
    In the process I got several warnings for incorrect partition schemes I was going to choose, and that helped to do things right.

    So I created a working system, and restore backups with nfs.

    Funny thin is, when I hook the disk so created to my own system, it sees the disk, but not the partitions... It's a funny world, UEFI...

    Again, thanks a lot for your good advice!!

    It is F12 in my case, and I used it several times during this thread. I still call it "Go into BIOS", thinking it is an UEFI BIOS, but from your quote I gather that's incorrect.

    Did so, see my last post in this thread. Thanks!

    UEFI and BIOS are two different things that serve the same purpose but in different ways UEFI has legacy capabilities so it can look and work like the older BIOS standard. UEFI has many advanced features not found in a BIOS.
