Windows 7 x64 won't startup

[juandavidb]

Hello and thanks in advance for your help!

While playing suddenly the blue crash screen showed up telling me some bad news. The error was "KERNEL_DATA_INPAGE_ERROR. When I tried to startup again the laptop didn't make it to the microsoft windows startup screen. The screen just remained blank. I thought it might be a cooling issue so I went to bed and let the laptop rest. But today I woke up and tried to start it up, at least it showed the message of starting up windows normally or try the system restore. When I tried starting up windows normally it took a couple of minutes and then it went to system recovery. When I tried starting up in safe mode the same happened.

So I let the system recovery figure out what was happening but it said it couldn't fix the problems. When checking the problem details it said "Problem Signature 07: CorruptRegistry". So I tried to fix MBR with no luck. Then I kept looking for an answer and I found SFC/SCANNOW. I'm stuck here, I went to command prompt and did that scannnow, but it has taken over 2 hours and nothing has happened.

I can't reinstall windows because it won't let me upgrade if I don't do it from Windows. And I can't perform a custom install because I will lose all my data!

Thanks for your help and sorry if I'm bothering!

Work through these steps for when Windows 7 fails to boot.

If the repair steps fail all that you need to copy out your files, Clean Reinstall Windows 7 Factory OEM or run Factory Recovery is there.
