Description Alexandre Oliva 2006-01-13 17:22:02 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.8) Gecko/20060103 Fedora/1.5-4 Firefox/1.5

Description of problem:
If I try to recover from bug 127557 on the newly-booted session, issuing on the rawhide grub the following commands:

(grub) root (hd0,0)   # the FC4 /boot partition
(grub) setup (hd0)

the system will become unbootable.  On a Dell Inspiron 8000 (PIII 1.0GHz), attempting to reboot will print blanks over and over, and finally print a portion of the BIOS and freeze.  On a Compaq Presarion R3004US (AMD64), it will just sit there forever.

If grub can no longer be used to fix older installs, this should probably be documented somewhere and, ideally, grub wouldn't let you shoot yourself in the foot like that.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Tell rawhide grub to setup the MBR to boot from an FC4 /boot partition

Actual Results:  It will happily render the system unbootable

Expected Results:  It used to work.  If it no longer does, it should probably tell you so, or even refuse to break stuff.

There's never been any guarantee for this to work, you've just been lucky and
_happened_ to have it work.
