The file is possibly corrupt. The file header checksum does not match the computed checksum.

My Laptop is a Toshiba Satellite L875-S7110, WIN 8 OS, 64it. I was doing a total reset, everything started out fine, got to the 3rd disk, it ran a little bit, then kicked it out asking for the next disc. The copies I made only produced 3 disks. I made more than one copy for spares, maybe I should have put the 3rd disk of the 2nd set of the copy I made, but I started over, made it again to the 3rd disk, pc restarted itself, but that is when the checksum error showed up. Is there anyway to get into command prompt and fix this error.

There might be a factory recovery partition on the Toshiba's hard drive.

Turn the laptop off.

Press and hold the 0 (zero) key down then press the power button.
