Hi and :welcome:

When running xPUD, if the USB drive is not visible, pull the USB drive out and reinsert it. This will allow xPUD to detect and recognize the USB.

Follow those parts of the following instructions you have not done:

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 to determine the reason for the restart loop.

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:

    Userinit.exe

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

    explorer.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
  • Lastly type bash query.sh
  • Press Enter
  • After it has finished a report will be located at sdb1 named RegReport.txt
  • Plug that USB back into the clean computer and post the contents of the report.txt, filefind.txt and RegReport.txt in your next reply. If too large, attach the files to your replry.
