openSUSE 11.4, I have boot partition on pendrive.
The problem is when I boot computer, grub immediately shows error "file not found" (I have no clue which file) and switches to "rescue mode".
I can boot computer from another pendrive, but I would like to use the original one (the one mentioned above). I tried to refresh grub using Yast, or manually by executing
grub --batch < /etc/grub.conf
or by copying all the files from working pendrive to the non-working (editing device.map after that), still no success, "rescue mode" is all I see.
I know one way to rebuild the content of the pendrive (it contains only boot partition) by reinstalling entire system again, and this will force building boot partition again correctly, but I am looking for something more clever.
So, how to rebuild entire boot partition+grub, not just polish 2 or 3 files within it.
