If you're not 100% sure that Windows got wiped out, open a terminal in your installed LL 2.6 and run this command to see if it finds Windows:
If it says it found it, run this command to update grub and hopefully you end up being able to boot into it again:
If LL 2.6 did get installed over Window XP then you'll unfortunately need to re-install Windows because many of its system files got overwritten by the new install. If there are data files that you need to recover from there you may be able to recover some/most of them using
photorec. Probably best to boot from your LL 2.6 DVD/USB to do this. You'll also need somewhere to direct the storage of recovered files -- eg. a large USB stick, external HDD, or 2nd HDD in computer with room for the files. (Don't try to save recovered files to the same drive that it's recovering them from.)
Read through info and documentation on Photorec site and look for possible Youtube tutorials so you know what to expect. Then boot from your live LL DVD/USB, open a terminal and run this command to install the program to the live environment:
Code:
sudo apt-get install testdisk
Photorec is included with the installation of Testdisk. To run it open a terminal and enter:
(If get message saying you don't have permission to run it, try again using "
sudo photorec". I can't remember if that's necessary or not.)
It will be a slow process, so just wait until it completes (possibly hours depending on size of drive and amount of files recovered). Limiting the file types that you want to recover will save some time and make sifting through the results easier on you.
Note: recovered files will probably not have original file names, so will take time to manually go through what it found to find files you want to keep.
When ready to re-install OS's, do Windows first, then LL. Windows will likely use entire drive, so you'll need to shrink it before installing LL. Good tool for that is
MiniTool Partition Wizard. (You can use GParted from LL DVD, but better to use a Windows-based tool.) Set Windows up the way you like, install whatever software you want on it, then do yourself a favor and create a backup image of it to make life easier if you ever need to restore it (or fix it) again.
Macrium Reflect is a good tool for that. Here is a post with tips on how to use it:

Once done with above, go ahead and install LL again. It should see the free space on drive (after you shrunk Windows) and offer choice to install "Along side" Windows. If you choose that it will use the free space and install to it.
P.s. If computer originally came with XP on it, then no need to worry about possibility of UEFI firmware on motherboard. If you installed XP on a relatively new computer (2011-12 or newer), then it
might have UEFI firmware. If that's the case, you need to set the boot mode to "CSM" (or "Legacy") because Win XP can not be installed in UEFI/EFI mode. The tutorial for a UEFI mode install will not apply in your situation -- just follow normal install procedures for both OS's.
