GRUB does not boot windows


My GRUB has been messed up somehow...
Turned out hd0 and hd1 had randomly switched places!
I reinstalled GRUB onto the harddrive, and now it boots perfectly - into all operating systems apart from Windows!

When I boot into Windows, it says Starting Up... then a cursor blinking
I've tried changing the commands before booting and reinstalling GRUB, but it doesn't budge.

The strange thing is, Windows is bootable, because when I boot directly into it from the BIOS, it starts up.

Here is my /boot/grub/menu.lst file:

Code:
# menu.lst - See: grub(8), info grub, update-grub(8)
#            grub-install(8), grub-floppy(8),
#            grub-md5-crypt, /usr/share/doc/grub
#            and /usr/share/doc/grub-doc/.

## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not use 'savedefault' or your
# array will desync and will not let you boot your system.
default		6

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout		10

## hiddenmenu
# Hides the menu by default (press ESC to see the menu)
#hiddenmenu

# Pretty colours
#color cyan/blue white/blue

## password ['--md5'] passwd
# If used in the first section of a menu file, disable all interactive editing
# control (menu entry editor and command-line)  and entries protected by the
# command 'lock'
# e.g. password topsecret
#      password --md5 $1$gLhU0/$aW78kHK1QfV3P2b2znUoe/
# password topsecret

## default kernel options for automagic boot options
## If you want special options for specific kernels use kopt_x_y_z

## default grub root device
## e.g. groot=(hd0,0)

## should update-grub lock alternative automagic boot options

## additional options to use with the default boot option, but not with the
## alternatives
## e.g. defoptions=vga=791 resume=/dev/hda5

## should update-grub lock old automagic boot options

## Xen hypervisor options to use with the default Xen boot option
# xenhopt=

## Xen Linux kernel options to use with the default Xen boot option
# xenkopt=console=tty0

## altoption boot targets option
## multiple altoptions lines are allowed
## e.g. altoptions=(extra menu suffix) extra boot options
##      altoptions=(recovery) single
# altoptions=(recovery mode) single

## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
## alternative kernel options
## e.g. howmany=all
##      howmany=7
# howmany=all

## should update-grub create memtest86 boot option
## e.g. memtest86=true
##      memtest86=false
# memtest86=true

## should update-grub adjust the value of the default booted system
## can be true or false
# updatedefaultentry=false

## should update-grub add savedefault to the default options
## can be true or false
# savedefault=false

sda1 is where Windows is
sda2 is another partition
sda3 is Gentoo (which isn't appearing on fdisk -l) and I will add this to grub later when windows works!
hdb1 is Ubuntu 8.04
hdb5 is swap

Your fdisk output shows xp on sda while your Grub sees it on (hd1). I would suggest you change your xp menu.lst entry to:

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