I've installed 2 disks (sda=4TB, sdb = 1TB)
sda is partioned as gpt while sdb is msdos.
I installed grub2 on both disks (sda => Leap15.1, sdb => Leap 15).
Installation finished. No error reported.
When I now start the PC the bootmanager is always started on sdb although the
boot sequence should be sda -> sdb
But when I insert the installation CD and select 'Boot from Hard Disk' the
correct bootmanager is started indeed. So obviously the boot partition is
correct on sda.
It looks like the MBR on sda does not point to the boot partition. I've read
something like that grub is split into stages and stage1 should still be
written into the MBR. Is this correct? If yes, could it be that stage1 is
missing in the MBR of sda and how could this be corrected?
