Please help me with my problem, i'm a complete noob at this.
i had xp64 installed on a SATA2 250gb. I added a slave IDE80gb drive just to put linux on.
my xp works fine, and so i continued to install fedora core 4.
the installation went smoothly and works perfectly, the only problem is that now i can't boot windows!
when grub loads at bootup, i have a choice between windows xp64 and fedora core.... obviously fedora boots and windows doesn't.
This is 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 (hd0,0)
# kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
# initrd /initrd-version.img
#boot=/dev/hdb
default=1
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Fedora Core 64 (2.6.11-1.1369_FC4)
root (hd0,0)
kernel /vmlinuz-2.6.11-1.1369_FC4 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.11-1.1369_FC4.img
title Windows XP 64
rootnoverify (hd1,0)
chainloader +1

the device map file is as follows:
# this device map was generated by anaconda
(fd0) /dev/fd0
(hd0) /dev/hdb
(hd1) /dev/sda

sda is my sata2 drive, hdb the ide one.
When i select windows grub displays the following:

booting 'windows xp 64'
rootnoverify (hd1,0)
chainloader +1

it just hangs on this screen.....
what do i need to change in the grub.conf for it o recognise the windows installation on the 250gb sata2 drive?
also look at this if at all useful: (fsdisk -l)

i have my 250gb drive split into a C: (operating system/program files) and D: (general storage)

please help me get both os' to boot, any replies would be most appreciated.

Try adding this to the menu.lst file;

title Windows at sda1
rootnoverify (hd1,0)
map (hd1) (hd0)
map (hd0) (hd1)
makeactive
chainloader +1

Try chainloading to your Windows XP like:

chainloader (hd1)+1

or

chainloader (hd1,n)+1

where n is the partition number on the hard disk. The map commands didnt help me. The chainloader command worked well.

Applied the fix to a second machine today, the map commands were necessary on this machine. Full text was:

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

Config was:

SATA0: Enterprise Linux 3.0 with grub (from Powerquest drive image. Bootable 80 Gb image)

SATA1: Windows XP Pro. (From CD, was only hdd in machine during install)

Also checkout http://www.gentoo.org/doc/en/grub-error-guide.xml

Problem 16 was got me going.

I can confirm that this works very well with Ubuntu 5.10, thanks for the tip.

Here is the original menu.list generated on install:

title Other operating systems:
root


# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sda1
title Microsoft Windows XP Professional
root (hd2,0)
savedefault
makeactive
map (hd0) (hd2)
map (hd2) (hd0)
chainloader +1


And here is the edited list:

title Other operating systems:
root


# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sda1
title Microsoft Windows XP Professional
rootnoverify (hd1,0)
savedefault
makeactive
map (hd0) (hd1)
map (hd1) (hd0)
chainloader (hd1)+1

So, these were all sata drives? Nice! I think I get it. Good find padmoz!
