I plan to install XP pro on my xa2528. the PC comes with 2 partitions on the HD

I download all the drivers for this

I saw somewhere a tutorial..."install XP on 2nd partition...then repair VISTA..."
but, to repair VISTA I must boot on the vista install DVD, unfortunatly, I just have the 3 DVD resulting of the 1st use of the laptop (3 x recovery DVD).
Using these DVD leads to restore the laptop to its initial state, erasing all datas even on the D: drive (no other option at all).
Can I make a bootable Vista install DVD from these 3 recovery DVD ?
How can I proceed ?
Regards.
