Also, changing registry files can be VERY DANGEROUS... I would only do it as a last resort before reinstalling Windows 7.

I first booted from the Windows 7 install disc to get to the system recovery console. I then selected Command Line. From there, I had to change from the X: drive to the C: drive by typing "C:". I then typed "cd \windows\system32\config" to get to the registry file directory. By typing "dir" I could see that two of the five hive files (default, sam, security,software, and system) had recent copies with an "rmbak" extension: default.rmbak and software.rmbak. I then executed the following commands:

ren software software.bak
copy software.rmbak software

ren default default.bak
copy default.rmbak default

I would suggest you execute the "ren" then "copy" commands as above for any other hives that have "rmbak" backups with the same date/time stamp. This ensures your registry remains in sync. You can now reboot and see if your computer comes up.

Here is an alternative suggestion if you don't have these "rmbak" files (if the above worked, don't do these steps; these would be a last-last resort before reinstalling Windows 7). From where we left off above type "dir RegBack". See what the time/date stamp is on the hive files there. If recent (use your judgment; mine is a couple days old so I would have probably used it had I not had the rmbak files, as I hadn't installed much in that time), you could do the following to restore that backup registry:

ren default default.bak
ren sam sam.bak
ren security security.bak
ren software software.bak
ren system system.bak
copy RegBack\*.*

Reboot and see what happens. If this worked, you may have to reinstall any software that was installed after the time/date stamps of the files in the RegBack directory.

One final note: I did try to restore to an earlier restore point once I made the above fixes. It kept coming up with an error. Therefore, I suggest creating a new restore point once the computer recovers, just so you have a clean one.
I need to add my name to the list of people that this worked for. Never would have thought that this would have fixed my issue but the next step was OS reinstall. I had a c000021a BSOD on boot. After running a CHKDSK, SFC (from WINRE without success). I was able to run the alternate method which had a backup from 2 prior to it happening. I printed this out and it is already in my Tech Cookbook for future use.
I appreciate the post my good friend!

Hallo guys,
I just joined cause I have problems with this blue screen. I made bootable USB with my Windows 7 64 bit and I tried to apply jbaileyn's solution but I can't change X:\Sources> to any other letter. Also, my Windows is on D partition, not on C.
System Recovery Options recognized Windows 7 on D partition but when I try to do System Restore, I get that "You must enable System Protection for this drive." message and it is related to C drive (again, my Windows 7 is on D)

I remember the cause: I did a registry clean with one old software that does not support 64bit systems. And now I feel so stupid.

Anybody has an idea what to do?

Again, I would like to apply jbaileyn's solution but when I type C: or D: it says "The syntax of the command is incorrect." and it goes back to X:\Sources>

Thanks for any suggestions!

Thank you jbaileyn!! You, sir/madam, win the Internet... the whole thing! Struggled through a bunch of things until I found this thread. Worked first time. (Once I realized my primary hdd was actually D:, not C:, spazzed out for a second.)

Spent 12 hours straight, trying to fix this laptop again. Tried every trick in the book. I will put Linux on when the warranty expires next year.

I ran my main Linux server for a week with no valid partition table, fat thumbed a command and destroyed it. The OS did not care if I killed the table, so I mirrored a drive, set-up grub and rebooted, like new again. It is a critical system with 32TB of storage on it -- has all my backups and data for a dozen years.

When it comes to the laptop, it seems I do more work keeping Windows 8.1 running than I do getting work done with it. Your post saved me! Worked like a charm. Cannot thank you enough.

DavePHL's is the preferred solution but jbailey's should work for most.

System Startup

Having spend the last several days in an endless loop of Startup>Automatic Repairs not working to solve a BSOD, I want to publicly give a huge THANK YOU to jbaileyn for his solution after I had run Norton Registry Clean-up that resulted in the BSOD and no amount of solutions would fix the problem. Just like faceman had reported in his later post, my problem arose immediately after running the Norton registry clean-up process which end in a "please restart your computer" - that when the mess begins. My advice is DO NOT RUN NORTON CLEAN-UP under any circumstances. Also, I must report that my experience after contact with Norton Support (who caused the problem) was absolutely abysmal - their advice was to contact either the manufacturer or Microsoft. When I asked them to explain to me where the registry back-up file was kept - they couldn't or wouldn't. (I knew there must be a backup somewhere because the message generated before running Registry Clean-up is along the lines of "creating registry backup"). I then demanded that they either escalate the matter to a higher level or let me talk to a Manager. The response - you'll have to call back!!!
To jbaileyn you answered the questioned that Norton wouldn't - again a huge thank you to you and forums like Seven Forum for providing many many solutions to user's problems and filling a space that the big guys like MS and Norton refuse to without charging an arm and a leg.
