Problems booting WinXP

[Elver Loho]

Hiya!

I dualboot Linux and Windows XP on this computer. At least I try to.
The problem is, GRUB refuses to boot up WinXP here. Complains (if I
remember correctly) about illegal devices. Windows XP is on a logical
partition and GRUB can't seem to be able to get at it.

Here's the file system as reported by fdisk:

Disk /dev/sda: 200.0 GB, 200049647616 bytes
255 heads, 63 sectors/track, 24321 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

  Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1          13      104391   82  Linux swap / Solaris
/dev/sda2              14       24320   195245977+   5  Extended
/dev/sda5              14         140     1020096   82  Linux swap / Solaris
/dev/sda6   *         141       10339    81923436    b  W95 FAT32
/dev/sda7           10340       24320   112302351   83  Linux

And the fstab:

address@hidden:~# cat /etc/fstab
# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
/dev/sda7       /               reiserfs notail          0       1
/dev/sda6       /windows        vfat    defaults        0       0
/dev/sda1       none            swap    sw              0       0
/dev/sda5       none            swap    sw              0       0
/dev/hdd        /media/cdrom0   udf,iso9660 user,noauto     0       0

This is my work computer and I had a wholly different partitioning in
mind, but, meh, the guys at the shop can't read and I unfortunately
don't have the time to reinstall everything.

The problem, then, seems to be that GRUB (0.95, Ubuntu) can't read the
Windows partition. Linux itself can. In fact I have it mounted right
now.

The entry for booting Linux reads:

title           Ubuntu, kernel 2.6.12-10-386
root            (hd0,6)
kernel          /boot/vmlinuz-2.6.12-10-386 root=/dev/sda7 ro quiet splash
initrd          /boot/initrd.img-2.6.12-10-386
savedefault
boot

This, however, doesn't seem to be working:

title           Windows XP
rootnoverify    (hd0,5)
chainloader     +1
makeactive
boot

Could someone point me in the right direction as to what I need to do
in order to boot WinXP?
