### BEGIN AUTOMAGIC KERNELS LIST
## lines between the AUTOMAGIC KERNELS LIST markers will be modified
## by the debian update-grub script except for the default options below

## DO NOT UNCOMMENT THEM, Just edit them to your needs

## ## Start Default Options ##
## default kernel options
## default kernel options for automagic boot options
## If you want special options for specific kernels use kopt_x_y_z
## where x.y.z is kernel version. Minor versions can be omitted.
## e.g. kopt=root=/dev/hda1 ro
## kopt_2_6_8=root=/dev/hdc1 ro
## kopt_2_6_8_2_686=root=/dev/hdc2 ro
# kopt=root=UUID=d3a99ae1-3422-49db-99b4-81f934aee4e3 ro

## default grub root device
## e.g. groot=(hd0,0)
# groot=d3a99ae1-3422-49db-99b4-81f934aee4e3

## should update-grub create alternative automagic boot options
## e.g. alternative=true
## alternative=false
# alternative=true

## should update-grub lock alternative automagic boot options
## e.g. lockalternative=true
## lockalternative=false
# lockalternative=false

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

## should update-grub lock old automagic boot options
## e.g. lockold=false
## lockold=true
# lockold=false

## 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

## specify if running in Xen domU or have grub detect automatically
## update-grub will ignore non-xen kernels when running in domU and vice versa
## e.g. indomU=detect
## indomU=true
## indomU=false
# indomU=detect

## 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

## ## End Default Options ##

If windows is on sdb1, and you are booting from sda first, then add this to the end of menu.lst:

title windows
rootnoverify (hd1,0)
map (hd0) (hd1)
map (hd1) (hd0)
makeactive
chainloader +1

Also, it appears that these statements mean grub will not appear unless you press Esc superfast! You may wish to modify them, especially by placing a hashmark (#) in front of hiddenmenu, and changing the timeout to 3.

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

add the above to the end of your menu.lst file if you are booting first from sda in BIOS.


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

if you are booting first from sdb in BIOS add this at the end of menu.lst

you can edit the menu.lst file by opening a terminal and running
gksu gedit /boot/grub/menu.lst

after adding the entry that applies to you click save then close the file and reboot to see if you can boot windows.

thanks merlin you beat me to the punch :D :popcorn:

[merlinus]

Yeah, but twice is nice!

BTW, if the OP is booting from sdb, does he need the map statements?
