Win 7 stuck on boot

hmm. I did another test later today and got different results.

Problem signature:
Problem Event Name: StartupRepairOffline
Problem Signature 01: 6.1.7600.16385
Problem Signature 02: 6.1.7600.16385
Problem Signature 03: unknown
Problem Signature 04: 21200667
Problem Signature 05: ExternalMedia
Problem Signature 06: 2
Problem Signature 07: NoRootCause
OS Version: 6.1.7600.2.0.0.256.1 Locale ID: 1033

I looked at the repair log and it says

Unspecified changes to system configuration might have caused the problem.

Repair action: System files integrity check and repair
Result: Failed. Error code = 0xa
Time taken = 6240 ms

"Unspecified changes to system configuration might have caused the problem." is our clue the OS has taken a big hit. I can't guess what hit it but so far with what you've written it's the same old answer no one wants to read or hear.

I might as well give some background info.

ANY and I mean ANY data recovery software is best tried after we try to copy out what we forgot to backup.

Here's one way -> http://www.howtogeek.com/howto/windows-vista/use-ubuntu-live-cd-to-backup-files-from-your-dead-windows-computer/

After you have copied what you can lose out, I would have written more about possible fixes but I have no details in this post about the make, model and if you have a Windows 7 DVD or those recovery media (which we try to not use.)
