grub

I have disk image with 2 partitions:

Partition 1 has cramfs file system (read only). This partition contains all system files of the OS
Partition 2 has ext3 file system. This partition has only configuration files that may be changed.

How can I install GRUB1 boot loader on MBR.

I tried to copy first 446 bytes of my hard disk and copy GRUB files to the /boot directory on the 1st (cramfs) partition.

I cannot use grub-install because I have disk image and not disk itself.

Any ideas?

I just updated from 11.10 to 12.04, with no major problems (it took a while to get past a request to restart ssh, mysql and some other services, but I did no fiddling by myself, everything was done by the installer).
