Since you can still run the recovery partition, do that now and try the


cd  \windows\system32



(Prompt should change to show you are in C:\Windows\System32)

ren  mbackmonitor.dll  mbackmonitor.bad

then reboot. We might get lucky.

I keep getting the same blue screen. Is there anything I can do with the Hiren's Boot Cd or the G-parted Cd?

I'd be interested to see if you can boot from Hiren's and get into the miniXP.

Gparted will let you look at the partitions and tell you if the C:\ is set to be active and bootable.

OK that's good to know.

See if you can follow the instructions here:

http://support.microsoft.com/kb/307545

You can start at part 2 since the minXP gives you access to the files.

Hopefully the malware or Norton hasn't deleted your system restore points. Assuming you have some, pick one of the older ones.

At the end of step 3 it says:

Type exit to quit Recovery Console. Your computer restarts.


You should try to let it boot normally (remove the CD). IF it does boot OK then you don't need to do anything else on that page.

Preferably from a clean computer, I need you to download: gparted-live-0.10.0-3.iso (115.1 MB)


Create a bootable CD, 1 for Gparted from the ISO image. You can use ImgBurn do this.

Now boot off of the newly created Gparted CD.

Posted Image
You should be here...
Press ENTER

Posted Image
By default, "do not touch keymap" is highlighted. Leave this setting alone and just press ENTER.

Posted Image
Choose your language and press ENTER. English is default [33]

Posted Image
Once again, at this prompt, press ENTER

Posted Image
Is "boot" next to your OS drive?

If "boot" is not next to your OS drive under "Flags", right-mouse click the OS drive while in Gparted and select Manage Flags

In the menu that pops up, place a checkmark in boot like the picture below:

Now double-click the Posted Image button.

You should receive a small pop up like this:
Posted Image
Choose reboot and then press OK.

Now reboot into the Windows XP Recovery Console and execute the following commands:

  • fixmbr \Device\HardDisk0
  • fixboot c:
  • exit

Go back into the recovery console and type:

chkdsk  c:  /p

This should check your disk for errors. Perhaps we will get lucky and it will find something.

I ran that and it indicated that it "found one or more errors on the volume."
