Dual Boot Into Windows Trouble


Hello. I am currently running Ubuntu 7.04 with KDE and would like to be able to dual boot to windows xp. Originally, one of my friends set up this version of Linux on my computer. GRUB was was on along with it and windows was another boot option I originally had. However, I recently updated my Ubuntu using adept and in doing so, windows was replaced on the boot list by the update. In the end, I would now like to find a way to get windows back onto my boot list. I know this probably isn't enough information about my system to explain to me how to accomplish this, so if there's any other info you need please just let me know. Also, know that I hardly know what I"m doing with Linux still, so I may ask a few questions about the answers you give me. Thank you for your time.

The first thing needed is to find out able the disk landscape of your computer. As root run
Code:
fdisk -l
(That is lowercase 'ell', not 'one').

That should return a list of partitions, of which one or more hopefully contains your Windows stuff. Post the results here (in code tags, please).

Also, post your /boot/grub/grub.conf or /boot/grub/menu.lst file here (again, please be courteous, and use code tags)
From there, we can begin to piece the recovery process together.

Alright,
Code:
fdisk -l
Gives me the following:
Code:
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       12791   102743676   83  Linux
/dev/sda2   *       12792       24134    91112647+   7  HPFS/NTFS
/dev/sda3           24135       24321     1502077+   5  Extended
/dev/sda5           24135       24321     1502046   82  Linux swap / Solaris
I'm almost certain by knowing this that the second boot device is Windows.

Also, my /boot/grub/menu.lst is as follows:
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 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		3

## 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

I think you need to add some lines to your /boot/grub.nenu.lst file. Here is the end of mine...


kernel /boot/memtest86+.bin
quiet

### END DEBIAN AUTOMAGIC KERNELS LIST

# This is a divider, added to separate the menu items below from the Debian
# ones.
title Other operating systems:
root


# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/hda1
title Microsoft Windows XP Home Edition
root (hd0,0)
savedefault
makeactive
chainloader +1



See how it adds on an extra entry beneath the "### END DEBIAN AUTOMAGIC KERNELS LIST" line. My XP is on my hda1 partition, and so is called "hd0,0" in grub. To explain...
a = 0
b = 1

1 = 0
2 = 1

so...

hdb2 is 1,1
hda2 is 0,1
hda1 is 0,0
sda2 is 0,1

I would add an option in to your /boot/grub.nenu.lst like mine to read...


# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sda2
title Microsoft Windows XP Home Edition
root (hd0,1)
savedefault
makeactive
chainloader +1

Awesome, Windows XP now appears in GRUB.

In the end I added the following:
Code:
# This is a divider, added to separate the menu items below from the Debian
# ones.
title Other operating systems:
root

# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sda2
title Microsoft Windows XP Home Edition
root (hd0,1)
savedefault
makeactive
chainloader +1
to the /boot/grub/menu.lst

Thanks a lot for the help and knowledge. And I think it makes enough sense now that if I install another OS I don't think I'll need to ask for help. Thanks again.
