Grub doesn't install to partition boot record (PBR)
Binary package hint: grub2
What i wanted to do is to install grub into the PBR to be able to chainload it from the grub menu from the grub in the master boot record.
But grub is not installed into PBR, nor by the alternate cd''s installer nor by running the grub-install command with --force-Option from from the runnning system or from the live system. It says bloklists are not recommended, but "installation finished, no error reported". But theres is no bootable Grub then. Choosing the chainload entry in the MBR's Grub shows "Invalid signature".
