i do nto quite know check the windows Xp site thats what i did

well all i know, you can use a flash drive, sd card, or this thinggy there you can plug it into a usb port anf then it connects to this bigger thinggy where you can put in a floppy disc.

You can restore your factory defaults via the BIOS I believe. When your computer starts up, you should see something like PRESS F2 TO ENTER SETUP. Don't mess with anything here EXCEPT for Restore Factory Defaults or Format C:. You will also have to create a bootable drive, flash drive I would recommend. DO NOT FORMAT C: OR RESTORE DEFAULTS TILL YOU HAVE YOUR BOOTABLE DRIVE READY!!! All you'd have to do is put it in the computer as it boots (given removable media is set in your boot order)

I know, jargon jargon x3 Talk to me on Skype :D
