Don't worry, it shouldn't be a problem. Basically you need to boot a live CD (same Ubuntu version as your HD installation) and use GParted to shrink and move partitions to make space for Xp, then install XP, then restore your Grub boot code.

But first, would you download and run this do we can see exactly what your setup is? Post the RESULTS.txt here inside code tags (use # button):

If you have a decent amount of ram, you could consider running xp on a virtual machine inside ubuntu.
I'd advise this specially if you'll make a rather occasional use of xp.

# #
# Tab width: 8 spaces #
# #
################################################## ##############################
# #
# Usage: #
# ------ #
# #
# Run the script as sudoer: #
# #
# sudo bash ./boot_info_script.sh <outputfile> #
# #
# or if your operating system does not use sudo: #
# #
# su - #
# bash ./boot_info_script.sh <outputfile> #
# #
# To get version number and last editing date of this script, use: #
# (no root rights needed) #
# #
# bash ./boot_info_script.sh -v #
# bash ./boot_info_script.sh -V #
# bash ./boot_info_script.sh --version #
# #
# To get help running this script, use (no root rights needed): #
# #
# bash ./boot_info_script.sh -h #
# bash ./boot_info_script.sh -help #
# bash ./boot_info_script.sh --help #
# #
# To automatically gzip a copy of the output file, use (root rights needed): #
# #
# bash ./boot_info_script.sh -g <outputfile> #
# bash ./boot_info_script.sh --gzip <outputfile> #
# #
# If multiple versions of boot_info_script are detected in the same #
# directory, boot_info_script will list all versions found. #
# In that case you need to force boot_info_script to run a certain version, #
# by adding "--this" as first argument (root rights needed): #
# #
# bash ./boot_info_script.sh --this <outputfile> #
# #
################################################## ##############################
# #
# Features: #
# --------- #
# #
# * Look at each MBR and identify its boot loader: #
# - For GRUB and SuperGRUB: display the controlling partition. #
# - If the MBR is unknown, display the whole MBR. #
# #
# * Look at all partitions: #
# - Determine their type. #
# - Identify their boot sectors. #
# ° For GRUB: display the controlling partition and the offset of #
# the stage2 file as recorded in the boot sector. #
# ° For Syslinux: display the full version name, check if internal #
# checksum matches, display installation directory, #
# display offset of the ldlinux.sys file. #
# ° For NTFS and FAT: examine the Boot Parameter Block for errors. #
# - Identify the operating system installed on that partition. #
# - List boot programs. #
# - Display the partition table. #
# - Display the output of "blkid". #
# - Look in "/" and "NST" for bootpart codes and display the offset and #
# boot drive, it is trying to chainload. #
# - Look on "/" and "/NST" for stage1 files and display the offset and #
# bootdrive of the stage 2 files it is trying to chainload. #
# - Display boot configuration files. #
# - Is able to search LVM partitions if the LVM2 package is installed #
# ("apt-get install lvm2" in debian based distros). #
# - Is able to search Linux Software RAID partitions (MD RAIDs) if the #
# "mdadm" package is installed. #
# - If dmraid is installed, search all RAID drives, detected by dmraid. #
# #
# * When running the script, without specifying an output file, all the output #
# is written to the file "RESULTS.txt" in the same folder as the script. #
# #
# But when run from /bin, /sbin, /usr/bin, or another system folder, the #
# file "RESULTS.txt" is written to the home directory of the user. #
# #
# When the file "RESULTS.txt" already exists, the results will be written to #
# "RESULTS1.txt". If "RESULTS1.txt" exists, the results will be written to #
# "RESULTS2.txt", ... #

If you have a decent amount of ram, you could consider running xp on a virtual machine inside ubuntu.
I'd advise this specially if you'll make a rather occasional use of xp.
i'd just like to use windows xp for online game downloads. just a few, so would that be good enough?
and how do i get this virtual machine. :s

You posted the script & its changelog. See the instructions on the site you downloaded from. You run the script and it creates a results.txt that is all the partitions and boot info from your system. Post the contents of that back in code tags.

How much memory does your system have? Virtual machines need more memory and run a little slower. Ok for occasional use if you have lots of RAM. But do not plan on running games at full speed. Then dual boot works better but requires a full reboot to change from one to another.

Well, olfred told you really, little to add.

Whether a Virtual Machine would be enough or not, mainly depends on how demanding your games are (and how how picky you are :D ). Think only in a VM only if you have about 1.5Gb or more, so you can assign 0.5Gb to linux and 1Gb for your gaming XP, at runnung time.

BTW, to run a virtual machine you have to install a probram like virtualbox (http://www.virtualbox.org/wiki/Linux_Downloads). Then run it, and install xp inside this program. THen you can start xp from there. Linux is still running, so you can switch between lin-win at any time, without reboot.

Not sure if that will suit your gaming needs though.

i deleted windows xp a while back from duel booting.
now i would like it back... and have no idea how to do that and without losing my files.
help please. :confused:

Dual - meaning two - booting -

not duel booting

a duel (http://www.thefreedictionary.com/duel) is a fight or battle between two people

to have windows and linux on the same machine:

as you noticed there is the dual boot, so you might need to rerun an operating system installation, or dealing with partition, a strong solution
install wine (windows environment simulation) soft solution, light for your memory, might not work for your games (I still cannot make internet explorer working properly... RDP runs perfectly though)
virtual machine, heavy to run 2 operating systems on one, but flexible solution and safe

i deleted windows xp a while back from duel booting.
now i would like it back... and have no idea how to do that and without losing my files.
help please. :confused:
Ok, your bootinfoscript output looks good. :)
You already have a large partition, sda1, on the disk and it is already NTFS format. So I don't think you need to do any repartitioning unless you want to change the size.

So I think (oldfred will correct me if I am wrong) you just have to boot your XP CD and tell it to install to the first partition. Don't get the partition wrong or you will lose your Ubuntu data. Back up vital files up before you do this.

Once XP is installed, you won't be able to boot Ubuntu. So you will need to boot a 10.04 Ubuntu live CD/USB (it has to be the same version as on the HD) and reinstall Grub:
sudo mount /dev/sda5 /mnt
sudo grub-install --root-directory=/mnt /dev/sda

yes this problem is simple. if not directly parallel install 2 operating systems. we should use software to create virtual space to install anything you want.

No dice, eh?
How confident are you with partitioning? Have you used Disk Utility before?
It may be that because the sda1 boot sector has been overwritten by Grub, or for some other reason, XP is not happy to install there. Sometimes deleting the partition and replacing it with a fresh one will work.
Partitioners are sort of simple to use but also very dangerous if you make a mistake.
Oldfred or others may have a better informed approach.

The fdisk is saying it is NTFS with the boot flag but the top of the boot script sees it as ext3???

sda1: __________________________________________________ ________________________

File system: ext3
Boot sector type: Grub2 (v1.97-1.98)

So this inconsistency is causing a problem. If you have no data in sda1, it might just be easiest to delete sda1 and recreate it. reformat it as NTFS & set boot flag.

I might back up partition table first just to be safe.

sudo sfdisk -d /dev/sda > parts.txt

Then copy parts.txt to an external device.

yeah i lost alot of memory when i delete windows XP from my terminal... so that partition is untouched, and empty space.
i don't know how to fix it?

is sda1 the empty space, where windows XP may have been?
if so how do i delete it?

how do i get a partition table?

and that first coding and second do i put that into my terminal?

ughh.
am i allowed to ask for your skype or whatever IMing system you may have?
that would make this aloooot easier.
if you would be willing to do that? i'd really appreciate it.

If there is no data to recover from sda1.

If you use Ubuntu liveCD, can you use gparted to delete sda1 and then just recreate it and format it NTFS, and add boot flag?

Then you should be able to use the windows installer.

i deleted the used partition, was labelled 250GB Had Disk.
the liveCD is the one that i used to install ubuntu, right?

i'll try to do what you say... but sound confusing at the time.
i've written what you said down... wish me luck? D:
