Install WindowsXP Boot Camp Wrong Partition

[lfraser]

I did a very stupid thing. I installed Windows XP using Boot Camp. During my mind melt I deleted all the partitions except a single raw partition for Windows. Now Windows works fine but OSX is history. I have both Tiger and Leopard install disks that are basically useless since the system boots to windows when I try to boot from them. I get the message "cannot locate Mac OSX boot file"

Any ideas that for removing Windows and reinstalling OSX?

Thanks inadvance.
