Windows 7: Windows won't boot after update

Windows won't boot after update

At least, that's what I think. When I start the pc, windows will boot to the splash screen, hang hang for a minute and then reboot. Just before it does, I can hear the hdd spinning down.

Safe mode won't work, system restore won't work, loading last know configuration and system restore won't work.

Any suggestions?

I think this happend after a windows update. After I tried "repair you computer" I got a number of errors, the first 2 are 6.1.7600.16385. This is a windows update I think

Did you try repair options from booted external media - e.g. cd/dvd?

No not yet because obviously I can't find the dvd...Should I try a chkdsk from the dvd?

For future reference keeping a recent system image (or more) would enable you to get out of unforeseen messes. The problem could be anything from an installation issue like yours or virus problem to a HDD failure.

After running sfc /scannow /offbootdir=c:\ /offwindir=f:\windows it says it found some damaged files but could't repair them all.

Looks like a re-install then.

If SFC finds files it cannot repair, I would run it again at least two more times to see if it will repair them as a last resort before Clean Reinstall - Factory OEM Windows 7 - the steps are the same for retail.
