dual boot in xp

ok i was tryin to install suse 10.1 on xp pro 64 as a dual boot apparently i missed some detail because xp wouldnt allow it to install. i shut down the puter and retired for the night. next morning i turned on the puter having failed to remove downloaded suse iso. suse took over completely and eradicated windows altogether . any pointers? i mean if somthins already posted about this just tell me where to look im new here and still feelin around in the dark. ty and btw linux is beautiful
