ok so my HD crashed and since im on a long holiday i dont have my leopard disk, i downloaded a .dmg on windows xp(running windows on my mac

) i even burned it via transmac, trans mac gave me an error saying media full or something but it seemed to burn fine.
question: will leopard boot if i have windows xp already installed?
im thinking the windows bootloader could cause problems..
and any other tips for getting this to work.
