Re insert your linux software, I am not sure if suse does, but fedora has a special feature to just delete your previous windows partions. And if it doesn't or doesn't work, right click on your 'my computer' click 'manage' then click 'disk management' it should show both your linux and xp partitions on there, make linux is shown as the primary, but either way, go download a program that is compatible with linux, I think they converted "partition magic" for that and just run through that and delete your xp partition. Good luck.
