I just installed the WinXP Pro and Redhat Linux 9.0 on my laptop. I use GRUB as loader. I can boot into Linux without any problem. But GRUB just hangs there when I instruct it to boot into DOS(WinXP). The partition on my harddisk is:
MB
/dev/hda
/dev/hda1 ext3 125 /boot
/dev/hda2 extended 57106
/dev/hda5 NTFS 16387
/dev/hda6 NTFS 20481
/dev/hda7 SWAP 2047
/dev/hda8 vfat 2047 /work
/dev/hda9 ext3 16143 /

Win XP is on hda5.
My grub.conf is

# 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.

# kernel /vmlinuz-version ro root=/dev/hda9
# initrd /initrd-version.img
#boot=/dev/hda

map (hd0,0) (hd0,4)
map (hd0,4) (hd0,0)
rootnoverify (hd0,4)
chainloader +1

Every time I try to boot into WinXP , the screen shows:

map (hd0,0) (hd0,4)
map (hd0,4) (hd0,0)
rootnoverify (hd0,4)
chainloader +1

and just stay there.

Thanks a lot for your help,

What is that for?

map (hd0,0) (hd0,4)
map (hd0,4) (hd0,0)

Comment it and try again. Might work.

The original grub.conf did no thave the statement
map (hd0,0) (hd0,4)
map (hd0,4) (hd0,0)

and I can not boot into WinXP. I followed the instruction in Howto: Linux + Win9x with GRUB to use the above statements to map the XP partition(hd0, 4) to the first partition of the firs primary partition (hd0,0). It still does not work, same as before. I just found out that the (hd0,4) is the first partition of the extended partition, so I used partition magic to convert it to a primary partition. But it still does not work. In addition, I got some error message about my SWAP partition when I boot to linux.

Any suggestion is highly appreciated.

Thanks,

sean

Did you try the following code:
