What was the exact bootloader error you got? Where did you try to install the bootloader, master boot record? partition of Ubuntu?
What was on the other partitions you cannot see from windows? What filesystem? Were they windows or Linux? Did you reinstall xp to the same partition it had been on?
wen i try to use through live ubantu i can see an more drive.
I don't know what that means, you will need to clarify. Can you see your old partitions in Ubuntu?
