Uninstall OpenSuse

I would like to know how to uninstall OpenSuse from my hard drive and leave my Windows XP intact.

I can not get a pendrive with OpenSuse to consistently boot correctly, but I am currently using Puppy Linux.

Can someone help me ?

Thanks.

Fist off maybe we can help. Failure is often a matter of the video driver/chip set. If you want to attempt to fix this install tell use what video card/chip

Removing may depend on if you have a BIOS or UEFI machine. Procedures would be different. So??
