Hi Oliver
I ran boot_info_script. Its results (relevant parts) are as follows:
=========== Boot Info Summary: ==========
=> Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in
partition #5 for (,msdos5)/grub.
=> Grub 2 is installed in the MBR of /dev/sdb and looks on the same drive in
partition #2 for /grub.
So grub seems to be in sda as well as sdb but the (,msdos5) is strange...

Boot sector info: Grub 2 is installed in the boot sector of sda5 and
looks at sector 84018242 of the same hard drive for
core.img, core.img is at this location on /dev/sda and
looks on partition #5 for (,msdos5)/grub.
