Hello,
Needing help booting laptop. Had run into the Google redirect/audio ads/script error virus over the past weekend. While attempting to scan and fix that, my laptop suffered an unexpected reboot and upon starting up I received the Blue Screen of Death (Error code 0x0000007b -and other parameters-). It instructed me to chkdsk /f but that, of course, is impossible to do in its current state.

I ran Dell's System Recovery Console, performed chkdsk /r, and fixboot, but those didn't solve the problem.

Can anyone guide me through restoring the boot process so I can get my laptop running back to normal (without wiping my data files, which, as of right now, are still alive)?

Thank you

Microsoft Says...

http://aumha.org/a/stop.htm, click 7B in left column.

As you csn see, there are varying possibilities for cause.

Although not listed in the links above, it seems to me that this error also frequently occurs in malware situations where users are trying to self-fix.

System manufacturer and model?

Can you boot into safe mode? Can you access the BIOS?

Louis

Hi, :welcome:

We will need to view the system status from an external environment. You will need a USB drive and a CD to burn. There will be several steps to follow.

Download GETxPUD.exe to the desktop of your clean computer
  • Run GETxPUD.exe
  • A new folder will appear on the desktop.
  • Open the GETxPUD folder and click on the get&burn.bat
  • The program will download xpud_0.9.2.iso, and upon finished will open BurnCDCC ready to burn the image.
  • Click on Start and follow the prompts to burn the image to a CD.
  • Next download driver.sh to your USB drive
  • Also Download Query.exe to the USB drive. In your working computer, navigate to the USB drive and click on the Query.exe. A folder and a file, query.sh, will be extracted.
  • Remove the USB & CD and insert them in the sick computer
  • Boot the Sick computer with the CD you just burned
  • The computer must be set to boot from the CD
  • In some computers you need to tap F12 and choose to boot from the CD, in others is the Esc key. Please consult your computer's documentation.
  • Follow the prompts
  • A Welcome to xPUD screen will appear
  • Press File
  • Expand mnt
  • sda1,2...usually corresponds to your HDD
  • sdb1 is likely your USB
  • Click on the folder that represents your USB drive (sdb1 ?)
  • Confirm that you see driver.sh that you downloaded there
  • Press Tool at the top
  • Choose Open Terminal
  • Type bash driver.sh
  • Press Enter
  • After it has finished a report will be located on your USB drive named report.txt
  • Then type bash driver.sh -af
  • Press Enter
  • You will be prompted to input a filename.
  • Type the following:

    Winlogon.exe

  • Press Enter
  • If successful, the script will search for this file.
  • After it has completed the search enter the next file to be searched
  • Type the following:

    explorer.exe

  • Press Enter
  • After it has completed the search enter the next file to be searched
  • Type the following:

    Userinit.exe

  • Press Enter
  • After the search is completed type Exit and press Enter.
  • After it has finished a report will be located in the USB drive as filefind.txt
  • While still in the Open Terminal, type bash query.sh
  • Press Enter
  • After it has finished a report will be located in the USB drive as RegReport.txt
  • Then type dd if=/dev/sda of=mbr.bin bs=512 count=1


    Leave a space among the following Statements:

    dd is the executable application used to create the backup
    if=/dev/sda is the device the backup is created from - the hard drive when only one HDD exists
    of=mbr.bin is the backup file to create - note the lack of a path - it will be created in the directory currently open in the Terminal
    bs=512 is the number of bytes in the backup
    count=1 says to backup just 1 sector


    It is extremely important that the if and of statements are correctly entered.

  • Press Enter
  • After it has finished a report will be located in the USB drive as mbr.bin
  • Plug the USB back into the clean computer, zip the mbr.bin, and except for the mbr.bin zipped file, post the contents of the report.txt, filefind.txt and RegReport.txt in your next reply. The mbr.bin zipped file must be attached to your reply.
