HEllo!
I am on Fedora core 2. Grub out of the blues stops booting XP, that is, when I select the "other" option on the menu it prints the following:
Booting 'other'
rootnoverify (hd0, 2)
chainloader +1
I had no problem booting XP in the past.
Here is my grub.config file:

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/hdb2
# initrd /initrd-version.img
#boot=/dev/hdb
default=0
timeout=15
splashimage=(hd0,0)/grub/splash.xpm.gz
title Fedora Core (2.6.5-1.358)
root (hd0,0)
kernel /vmlinuz-2.6.5-1.358 ro root=LABEL=/ rhgb quiet
initrd /initrd-2.6.5-1.358.img

chainloader +1

hi there
have u changed u hard disk from primary master to slave or vice versa??

regards

I think you should add a 'makeactive' line right above 'chainloader+1'. At least that's what the GrUB documentation says: http://www.gnu.org/software/grub/man...#Chain-loading

I have not touched the jumpers since I bought the hard drive. After adding the makeactive line before chainload +1, no changes, I still can not boot XP.
