Error: 0x000000F4, Blue Screen, Registry error, can't Repair

original title: Error: 0x000000F4, BSOD, Registry error, can't Repair

I have a computer running Windows 7. I have been a long time user of Auslogics Boostspeed and never experienced any issues with the program before on 3 other computers, 1 of which also runs Windows 7. Running Boostspeed's Registry Defrag on this specific computer has caused something in the registry to cease functioning, causing a critical error when the computer is reset, resulting in a blue screen of death (which does the usual, memory dump, tell me something is wrong and that it is a critical error in a thread or otherwise and then provides the codes).

Apparently, a restore point can not be used because System Protection was never activated on the main hard drive, nor is there an option for factory restore or any other restoration functions via the System Recovery Interface. I can not enter Safe Mode or any version of Windows itself, though I can access the command prompt.

I have tried using System Restore from a CD. System Restore from boot options, I have tried every version of Safe Mode. I have tried using ubuntu to run Wine to execute Auslogics Boostspeed's Recovery Program but my Windows 7 is x64 so ubuntu is useless. I have tried recreating the bcd.

All I want to do, is find a way to get to the recovery point made by Auslogics or turn on System Protection via command prompt or something so I can use the recovery point made by Auslogics through System Recovery.

I am posting from another computer, the computer this happened on is a Lenovo IdeaPad Y560 which was running Windows 7 Home Premium. The thing is basically a paperweight at the moment, so I can not provide the precise codes listed on the BSOD unless there is a way to do so via command prompt.

I am willing to reformat or reinstall Windows 7 but I would really like for it to be a last option as I am a college student and the loss of data would force me to drop my current class. Any help anyone can provide would be much appreciated.

You can back up your files while in the Safe Mode Command Prompt but this requires skills in working an a Console environment.

Restoring an older version of the registry is an involved process and it works only when booting the machine with a Repair CD or a Windows installation DVD. Burning a Repair CD is a five-minute affair - why not ask a friend? If this is not an option then you can download one from this link. This is a somewhat involved process. http://neosmart.net/blog/2009/windows-7-system-repair-discs/.

When you finally manage to boot the machine with some boot CD then you can use this procedure to restore your registry. Ask a computer-savvy friend to assist you if you lack experience in this area. Note that it may reset your password to an earlier value.
1. Keep tapping F8 during the early boot phase.
2. Select Repair from the menu.
3. Log on as Administrator if prompted.
4. Select Repair when prompted.
5. Select the Command Prompt.
6. Identify the correct drive letter for your Windows installation. It could be a drive other than C: but it won't be X:. You do it by typing the commands
    dir C:\Win*
    dir D:\Win*
    dir E:\Win*
    until you find the Windows folder.
    I will call that drive "Q:".
7. Type these commands:
    cd /d Q:\windows\System32\config
    xcopy *.* Q:\RegBack\
    cd RegBack
    dir
8. Examine the dates of the Software, System and SAM files. Were the files created before or after your problem became apparent?
9. If they were made before the problem became apparent then you can type these commands:
    copy /y software  ..
    copy /y System  ..
    copy /y Sam ..
    (the two dots are part of each command)
10. Reboot normally. If things do not work out then you can backtrack by copying the original registry files from Q:\Regback to Q:\Windows\System32\config.

At Step 5 you could, in fact, attempt a System Restore.

just worked I am so happy that I can kiss your head friend Frederik Long.

Thanx a lot :)
