Can anyone help me to fix a laptop with this error:
Bug Check 0x75: CANNOT_WRITE_CONFIGURATION
I completed a scan using Malwarebytes and it found numerous trojans, which it quarantined and deleted, then I restarted the system and the BSoD appeared. Can't get past it, even when trying to log in under Safe Mode.
Any help is appreciated...

Thank you for your advice, however, I have already run my scans and cleaned the system. Additionally, when I restarted after the last scan, I have not been able to boot to Windows. System displays the blue screen of death and I can't get past it, even when trying to log into the safe mode.
This is where I need the help!

Any technical information on the BSOD or is it flashing to fast to see?

Bug Check 0x75: CANNOT_WRITE_CONFIGURATION
0x00000075 (0xc0000005 0x8537009, 0xf78a6e0, 0xf78a60dc)
That's it. It sits on the blue screen no matter how I try to boot the system.

This is a long shot but can you boot to the Advance Boot Menu where you found the safe Mode option and there should be another option named Last Known Good Configuration
Have you tried this?
Now if this doesn't work we can try a system restore using the Recovery Console.

If you have Windows XP CD...

1. Boot from the CD.
2. When the text-based part of Setup begins, follow the prompts. Select the repair or recover option by pressing R:



3. You'll find yourself at this screen:



4. Once you are at the Recovery Console you will be given at least one choice of Windows installations. Normally the choice you want is the number 1 choice. Click the number 1 key at the "top" of the keyboard and click enter.

NOTE: at this point your numbers to the right of your keyboard are turned off. If you insist on using these keys for your numbers remember to hit the Numbers Lock key before clicking a number over there or your computer will automatically reboot and you will have to wait through the previous steps to get back to the console.

5. You will be given a message asking for the administrator password. Unless someone or something has messed with your computer there is no password so you just click the Enter key.

6. This will bring you to a prompt that says:

C:\WINDOWS>

7. Type:

cd \

Press Enter

Note: between "cd" and "\" there should be a "blank space" otherwise the command won't work

8. The prompt should now say:

C:\>

9. Type:

cd system~1\_resto~1

Press Enter.

Note: If it gives an error "Access Denied" while accessing the folder, follow the method below

Type: cd \

Press Enter

Type: cd windows\system32\config

Press Enter

Type: ren system system.bak

Press Enter

(note the spaces between ren and system, and then between system and system.bak)

Type: exit

Press Enter

now the computer should restart, then follow steps 1-6

10. Type:

dir

Press Enter

NOTE: When you hit enter it will list all the restore points folders like "rp1", "rp2" we have to see the last restore point to copy the file from a recent backup. If the restore points have more than one page then you have keep on hitting the key to view the last restore point folder.

NOTE: It is a good rule of thumb to choose the files from the restore point folder which the second to the last one.

11. Type:

cd rp{with the second to the last restore point number }

Press Enter

Example: cd rp9. if rp10 is the last restore point

12. Type:

cd snapshot

Press Enter.

NOTICE: Now the command prompt will look like this:

c:\system~1\resto~1\rp9\snapshot

Note : restore point 9 assumed for clarity of the content.


13. Type:

copy _registry_machine_system c:\windows\system32\config\system

Press Enter

14. Type:

Exit

Press Enter.

Final note : If the above procedure won't solve the problem, repeat all steps, but in step 13 type:

copy _registry_machine_software c:\windows\system32\config\software

Alternatively, select different restore point.



If you don't have Windows CD...

Download Windows Recovery Console: http://www.thecomput...om/files/rc.iso
Download, and install free Imgburn: http://www.imgburn.c...hp?act=download
Using Imgburn, burn rc.iso to a CD.
Boot to the CD...let it finish loading.
When the "Welcome to Setup" screen appears, press R to start the Recovery Console.

Follow steps 3 - 14.

Thanks to Broni for the instructions

Sad to report that there are no .rp# folders after step 9. Time to wipe and reinstall WXP, unless you have more steps?

[rshaffer61]

Well before format is there data you want to save?

[PJBrake]

No, all data for this laptop was saved to server before I received it for repairs. So, clean install is my next step. Thank you for your assistance! On to the next job; trojan.vundo cleanup, Yay Me!
