Somehow my sisters IBM thinkpad laptop messed up, and before loading the OS on boot the screen would turn black and loose responsiveness. I managed to work out and locate the error that it coudnt find an operating system. Id had this problem before and it was solved by reparing the mbr. I booted up ubuntu live cd (the os is beside the point) and ran TestDisk to solve the problem, however it gave me this error
