I have a laptop that went to try to boot it, it comes up with a screen that give me a choice of starting in safe mode, normal mode or last known good configuration. When I try either of the first 2 nothing happens, when I try lst know good configuration, it takes awhile, but finally I get a message of <Windows Root> \system32\ntoskrnl.exe. I also tried checking the hard drive through F2 setup and I get a message #1-07 Fail. I have tried taking the original OS disc and use Repair, it tells me when it's done to type exit and restart. But it all goes back to the begining problems. I have extremely important files on this drive and am at a loss as what to do. Can anyone help???????
