Offline SFC woes

So I'm trying to get a computer running, currently getting a black screen with a mouse when it boots to windows, and nothing else. Last time I had this, an offline SFC allowed windows to boot again.

To be clear, I mean loading up recovery from windows recovery environment, using the command prompt and typing sfc /scannow /offbootdir=d:\ /offwindir=d:\windows
where d:\ is the native windows install(confirmed from a dir command).

So after running this for five minutes, the system comes back with an error, windows resource protection could not start the repair service.
I'm kind of at a loss, I know this command will work from recovery since I've used it before on a different comp, same os, so there must be something I'm missing. Is anyone familiar with this kind of issue, or have any suggestions?

I'd try a regular Windows 7 repair. The SFC/Scannow may not work in situations where there is significant corruption OR it may be a drive issue and unrelated to the OS itself aside from possible corruption due to disk reads/writes or bad sectors.

Try running Seatools for DOS to determine if it's drive related. (Drive brand doesn't matter for these tests.):

If the drive checks out ok, try a Windows 7 repair which should not affect your personal files or applications:

That would work wonderfully if I had access to windows, unfortunately the problem is that I cannot access windows. Offline sfc works differently and this article does not address my issue.



The windows 7 repair wasn't coming back with any startup issues(I assume you meant repair startup, if not maybe I'm unfamiliar with what you mean by windows 7 repair).
The bad sectors was spot on, however. I did a thorough chkdsk and it found and repaired the issue, windows is booting properly now, thanks for the advice I usually disregard chkdsk because it never seems to fix problems!
