I know it's my own fault but can't see a way out. I made an entry to
grub.conf of an F7 system that I am currently building. The purpose of
this entry should be to launch BookManager. I have tried many variations
to no avail and at this last time I got the idea from some grub
documentation that I should code the entry as:
Title BookManager
map (hd0) (hd1)
map (hd1) (hd0)
rootnoverify (hd0,1)
makeactive
chainloader +1
All my (stupid) attemps did not launch BookManager but did no other
harm. It was not till I added the two map statements that I got the
problem that after the first attempt to load BM I was no longer able to
boot the F7 system. Clearly the statements had ruined my boot loader
somehow. Is there a way to rectify the damage? I had not expected that
this would cause a permanent damage to the system.
1. use grub's ability to edit the in-memory menu to delete and/or modify
lines.
2. use the grub command line to type the commands and boot manually. One
of the great things about grub is that anything it can boot, it can boot
without a menu.
system from CD, mount your system disk and edit grub.conf again.
