I had 2 partitions with 2 XP. I selected the 1st partition, formatted it, and installed Ubuntu 9.10 on it.
Now I can't boot into XP cz is showing me the XP loader of the XP that I deleted... I tried fixmbr and fixboot but with no effect.
In the beginning XP couldn't boot, but at least I could browse the folders from Linux. Now in the Disk Utility it's written unrecognised, unknown or unused.

Here it is:

Update: after playing with some partition boot CDs:

Here's a screenshot of GParted and Disk Utility:

Any ideas?
