How could I wipe it clean, never used windows.
When you turn on the laptop hold the DEL key (I think, I don't use windows much either) and then enter BIOS, select the CD Drive as the boot device (or usb if you're gonna install windows off of usb) and then restart the laptop with the boot cd inside and when you get to selecting the partition, click format for all of them and you've got a clean wipe.
That's the fastest way I know to do it.
