Windows 7: Windows 7 broken: can no longer log in...


22 Mar 2012   #1

Windows 7 Ultimate x64 SP1
 
 
Can no longer log in after unexpected reboot & startup repair!

Hi there,

Sorry if this post is quite long, but it summarizes a whole day spent attempting to fix my broken system

Back to office this morning I found my Windows 7 SP1 (Ultimate x64) rebooted and entered in the "startup repair" procedure. Was really weird to me considering I left it yesterday at night powered on, and that it is configured to hibernate later on in the night, and to wake up at 8 am, just before I arrive to office.
Moreover, other machines let me say that there were no power outage.

After it attempted to repair, I rebooted and landed on the Windows 7 Welcome screen, but with only one account, of which icon was empty (transparent), and no user name was proposed (to be fill in). So, I tried to key each of my accounts with associated PW, but all were denied access.

So, I spent the whole day to try multiple potential solutions found on the Net (including your forums), but I always ended up to the same issue: unable to log in. Here is what I've tried so far (not in exact chronological order):
- rebooted and tried "Last known good"
- rebooted with installation DVD, chosen "Repair":
* tried "startup repair"
* tried "system restore", took 10+ min. to restore the last Restore Point generated yesterday, but ended up with the same login issue
* tried "command prompt": let me see that all my 4 partitions are accessible with (apparently) all stuff in place
o chkdsk /b /r /v
o sfc /scannow /offbootdir:c:\ /offwindir:c:\windows, as per one of your tutorials, but was told that it could not start the repair service,
o sfc /scannow, but I'm always told that a system repair is pending and that I must reboot and try again...
o bootrec:
. /FixBoot: operation OK, but same issue anyway
. /FixMbr: operation OK, but same issue anyway
. /ScanOs: told me that it found 0 Windows installations
. /RebuildBCD: told me the same
o tried to rename currently present bcd & bcd.log*, as per another forum suggestion, and then rebooted
- rebooted in safe mode:
* but crashed with a BSOD just after displaying "Classupnp.sys"
* unfortunately my system is configured to restart after BSOD so I could not write down error number & other info,
* so, not knowing if "Classupnp.sys" was the driver currently loading or the last one properly loaded, I tried to replace it with the installation DVD one, but without success

I probably forgot some other attempts...

Anyway, I'm now out of idea, and my last resort is to reinstall Windows 7, but I would like to avoid it, hence why I hope that you'll find a way to fix my current installation.
BTW, I'm puzzled by the fact my system rebooted, the only reason I can imagine is that it crashes with a BSOD, and that tried to reboot. So, the cause could be a new HW, but I didn't install one recently (just moved a USB bluetooth adapter from a USB slot to another), or the consequence of a system update (but sounds not very likely), or some malware.

Precision: FWIW I must tell that my OS is configured to have "Program Files" folders and user profiles on other drives that the system one thanks to junction points :
- C: is the system and boot drive, "\Users" is a junction to "F:\Users", while "Program Files" (and its x86 counterpart) is a junction to "E:\Program Files"
- D: is dedicated to the swap file
- E: holds installed applications
- F: user data
It's running like this for, years.

Thanks in advance for your help

Do you hear any beeps?

Is your HDD clicking?

Have you entered setup options and ran an extend scan of your HDD?

sfc /scannow /offbootdir:c:\ /offwindir:c:\windows, as per one of your tutorials, but was told that it could not start the repair service,
o sfc /scannow, but I'm always told that a system repair is pending and that I must reboot and try again...

did you do the sfc/scannow command from "repair disk", "installation dvd", or by pressing F8 and enter "repair computer"? Don't do it using F8 as most of the time sfc/scannow doesn't work then. Sure your prompt was X: instead of C: when doing the command? Do a DIR C:\ in "recovery environment" to be very sure C: is indeed windows partition
