i have installed Windows XP in /dev/sda1 and linux fedora core 5 in
/dev/hda7(swap) and /dev/hda8(/).
grub detects fedora core 5. but while i select windows xp , it shows
error message .

my grub.conf :
# 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 (hd1,6)
# kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
# initrd /initrd-version.img
title Fedora Core (2.6.15-1.2054_FC5)
root (hd1,6)
kernel /vmlinuz-2.6.15-1.2054_FC5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.15-1.2054_FC5.img
title Windows Xp
rootnoverify (hd1,0)
chainloader +1
this file was origanally created by Fedora core 5 installation .while selecting windows Xp in grub, it shows a error and restarts the grub. how can i install both windows xp and fedora core 5 in such case.

please reply me soon in full detail(i am using linux for first time).

Does your Fedora core install boot and/or run properly? You have what looks like some errors or your written your post wrong. You say your swap is /dev/hda7, but you've got /dev/hda7 setup up as Linux, not swap. Your hexcode should be 82, not 83.

/dev/hda7 7837 7849 104391 83 Linux
should say..

/dev/hda7 7837 7849 104391 82 Swap
As far as your chainloading problems, check out this thread I found on another forum. They have some good advice.

Or if your lazy, here is a working grub.conf snippet from a guy with a similar problem,

title WinXP64
rootnoverify (hd2,0)
map (hd2) (hd0)
map (hd0) (hd2)
chainloader +1

Windows is strange because it always wants to be the first drive. You need to remap the drives so Windows can boot up. The lines below should boot up Windows.

title Windows Xp
rootnoverify (hd1,0)
map (hd1) (hd0)
map (hd0) (hd1)
chainloader +1
