rescue method missing

[Hadmut Danisch]

Hi,

I was just force to migrate from grub 0.97 to grub2 by a debian upgrade.

Well, manpages are poor and I made some mistake with installing grub. It
is not always obvious where to give a device path, a device like (hd0)
or (hd0,0). man pages and error messages should be more verbose.

However, I did not find a way yet to repair a system which does not boot
anymore. Whatever I try (use a LiveCD, mount the file systems, chroot
into), I still geht error messages from the grub programs about device
problems. Unfortunately, all those error messages don't give any hint
about what's the problem and how to solve, which is rather difficult
when using a LiveCD with a minimum of tools.

Please make the error messages more verbose, and please define a way
to rescue a system that does not boot anymore.

regards
Hadmut
