HiGrade notino l100 net book refuses to boot?

When I press F7 to recover it takes you to a recovery screen. this happened once before and the hard disc was formated and it cost big money to reinstall the OS by a techie.we do not have an OS disc can I re install the XP (service pack 3) system from my other laptop using a bootable disc in a usb external drive and the licence key from the notino?
The notino was is using XP too
