GRUB is not booting the correct partition in a dual drives system


I have a system with two hard drives.
On the first hard drive I have windows as the first partition, ubuntu on the second. On the second drive (which is sata) I have a windows partition. After installing ubuntu It would boot the windows partition on the second hard drive not the first. I could get windows to boot on the second drive by using (hd1,0) to try and get windows running on the first drive I have tried (hd0,0) and that does not work. (hd0,1) boots into linux. and linux recognizes the windows partition I want to boot as hda5.

The only solution I can think of at this time are either restoring the windows MBR (which I really don't want to do), or reload ubuntu which would mean I have wasted alot of time setting it up .

Any help would be appreciated,


oh, here is my menu.lst

# 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 change this entry to 'saved' or your
# array will desync and will not let you boot your system.
default 0

## 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

## ## 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=3ce00fb0-5221-4acd-b3d3-135610c5700f ro
# kopt_2_6=root=/dev/hda2 ro

## default grub root device
## e.g. groot=(hd0,0)
# groot=(hd0,1)

## 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

## 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

Remove the two 'map' lines from your Windows entry and add another matching Windows entry (XP on hda5) except instead of hd(0,0) -- which is your first drive -- use hd(1,0). The map entries are sort of redirecting your grub to the other drive. That should do it. However, if the first drive has Windows on the 5th partition, hda5, you will need to use hd(0,4) instead of hd(0,0).

Since your XP Pro on the SATA boots, why not just add the other Windows system to that one's boot.ini file? You'd have to let GRUB boot the SATA system, but that would just show you the Windows boot menu, and you could select the other XP system from there.

You say you've tried (hd0,0). Did your enry look like this:
Code:
title Microsoft Windows XP Professional on hd0,0
rootnoverify (hd0,0)
chainloader +1
If not, try it. It might work . . .

<edit>
Per Mr. Vega's entry, you may need {hd0,4) in the above snippet if your hd0 has xp in partition 5.

Yes, that suggestion should definitely work. You could have one XP entry in grub which would direct you to, instead of XP itself, just the Windows boot menu and from there you could select which XP installation you wanted to load.
Either one will do the job.

Thank you Mr.Vega and Mr.Trenholme. I am getting rid of xp on the second drive anyways, and I kinda like grub. I wish it looked a little nicer, maybe a frontend? I have tried hd0,4 but without the rootnoverify, I will see tonight.

Thanks again
