CF30 Mk1 XP to Win7 - advice for non techy pig

Hi all,

I have a CF30 Mk2 touchscreen and would like to upgrade to Win7. The toughbook was originally Vista (CoA sticker on bottom) but was bought with XP installed. I have an XP disc but no Vista disc.
Is it as simple as updating BIOS back to Vista and then clean installing Win7 from a disc, and then installing whichever drivers needed? Or do i have to update BIOS, then clean re-install Vista from a recovery disc before clean installing Win7? If so can anyone point me to where i can...
