Windows 7: System restore can't help: "Unknown bugcheck."

System restore can't help: "Unknown bugcheck."


A few days ago my windows 7 wouldn't complete boot. I got a blue screen, which said something like "a vital execution thread suddenly stopped."

Then windows ran System Restore, but it ended by saying it couldn't help!

It said:

"Unknown bugcheck.

bugcheck f4


I have trying to read up online ever since, and my head feels like it's going to explode! I thought I could reinstall windows 7 over the old one, but from what I have read, it seems I can't, and I have to start with a fresh harddrive. So I was going to buy a new harddrive, and reinstall. But since this is going to be a humongous amount of work, I wanted to ask you guys, if there is some way I can avoid some of it.

Is there a way I can get my system to work as it is? Or a way of reinstalling over it?

I tried to use a System Restore Point, but it claimed there weren't any! I was sure I had made one some monthys ago.

But the harddrive seems okay. I booted a small Linux which is called Tiny, and I could see all my files, and I tried opening some of them.

I tried running chkdsk /f on my harddrive, but it didn't seem, to help any...

Please help!

There is a way to install Windows 7 Professional and "below editions" on top of a current Windows installation; however, there are risks involved. Do you have current, restorable, backups of your Data folders and files or Data partition on external media?

Did you try the Restore point in Safe Mode? They can get screwed up in regular mode but be available and work in Safe Mode.

Did you try a SFC /scannow?

Bugchecks are really nasty.
