Dual boot with XP installation failure

[gold_finger]

See if you can repair Win XP booting using link from rokytnji.  If you can do that then you can just use the GParted program from live LL dvd to delete the Linux partitions that were made before and redo the installation.  However, because of possible complications noted in next paragraph, it might be better to wait until we see requested info below before trying to proceed.

If unable to repair XP boot, we'll need a bit more info after seeing what you posted so far.  I see that you have two hard drives and you said that you had a problem with the larger one, but put it in to access the data on it.  Main question is:  which of the two hard drives was Windows XP booting from before you installed LL?  Based on what you said, I'm guessing that the larger drive became unbootable at some point and you then installed XP to that 24GB NTFS partition shown on the smaller drive in order to have a usable system again.  Is that assumption correct, or completely off base?  Also, just so we know, do you have an XP install/restore disk?

At this point it's hard to guess what exactly is going wrong.  I suspect a combination of things are possible if assumptions above are correct.

• For whatever reason, LL's grub boot loader either didn't get installed correctly or was pointed to the wrong hard drive.
  
• It's possible, if you changed anything in the Bios settings, that computer is set to try booting from the larger HDD instead of the new small one and you're running into whatever problem you had with it before.
  

Those are purely guesses at this point.  Answer above questions and if possible describe in more detail what kind of problem you were having before with that larger HDD.  (That info may or may not prove useful.)  Also, boot again with live LL dvd, open a terminal again and run the following commands one at a time in the order shown:

Code:

sudo os-prober
sudo mkdir /mnt/one /mnt/two
sudo mount /dev/sdb7 /mnt/one
sudo mount /dev/sdb5 /mnt/two
ls /mnt/one
ls /mnt/two

Copy full output of all commands and paste back here.  Should have a good idea of how to proceed from there.
