Doomed to failure. os-prober doesn't consult the MBR; the referenced
README is there to consult for what it does do.
It would do no harm for your MBR on /dev/sda to be in a shipshape
condition as far as GRUB is concerned:
grub-install /dev/sda
Then a few checks with the following commands:
os-prober
linux-boot-prober /dev/sdb1
/etc/grub'd/30_os-prober

Maybe; then you put the data back. Before carrying out this technique you
could have a look for files such as /etc, /boot, debian_version, vmlinuz
and initrd.img.
Were you curious enough to try to boot "Debian GNU/Linux, with Linux
3.2.0-4-amd64 (on /dev/sdb1)"?
