Booting Windows XP from a new motherboard

Hi there -- I had my motherboard give me CPU INIT (which didn't allow me to boot up, basically my motherboard is dead) and I had to get a new motherboard -- going from Striker Extreme to Rampage ASUS.

I had windows XP 32bit installed on one of my hard drives at the time, but the windows xp cd I HAD was lost a while ago. So I recently bought Vista Ultimate 64bit (I have the proper specifications to run it) -- since i was planning on upgrading anyways.

Will my computer boot up to xp -- or will I have lost all the information that was on my hard drive?

If not -- will I have to install and reformat that hard drive, losing all my information in the process?

How do I reformat the hard drive if I cant even boot to xp?

Thanks

Your new mobo is the same that the old mobo? If it isn't you can not boot from XP. Boot fromo the vista cd, this create a folder named WINDOWS_OLD, all your files fromo xp are archived here, so, you don't lost all files, only programs and games...but you can also recover with active file recovery, need a licence, but is really good.
