My brother bought a laptop an older laptop for my niece its a toshiba protege M200. It has a non working copy of win 7 installed. So I need a bootable cd this thing doesn't allow you to boot from ssd card or usb thumb drives and I have a portable cd-rom and no dvd rom.I need to get to a command prompt to run magic jelly bean so I can get his win 7 key off of it then start the windows install from a folder. Any suggestions welcome
