I bought a Dell all in One computer which is rather nice. It doesn't take up hardly any room at all. My wife's Toshiba laptop had a hard drive failure. I bought a new hard drive for it, and followed Toshiba's instructions on installing the Windows 7 back up files. Very simple and easy. The only problem is, "the back up drivers are not signed, and Windows will not run unsigned drivers." If I press F8 and select, "run without signed drivers," it' runs great, except it will not update Windows 7. I checked on line and there must be a 1000 of complaints about Toshiba and their unsigned drivers. Toshiba says, "go on our website and download the latest drivers, but their latest driver are not signed either." So my question is, "how the hell did they get the drivers to work in the first place...?"
