Having recently also come across this problem, I think part of the answer might lie in the fact that one has to ensure that in "rescue" mode one can write to the system files. One does this by executing the following under the grub shell : mount -n -o remount,rw / After doing this I was able to edit fstab which had become corrupted and which prevented the system booting. I can also recommend the extensive help which you will find on the NU web site : http://www.gnu.org/software/grub/manual/ I've printed this out and now have it as a valuable resource for any future problems. -- This e-mail produced entirely under Linux.
