Please provide as much background information as possible on events leading up to this issue:
  • Do you have any idea what may have caused the system to become unbootable?
  • What was happening on the system before the problem arose?
  • Was there any sign of malware on the system, and were you attempting to remove it?
Re: black screen with blinking cursor on startup
This is often caused by a corrupt MBR (Master Boot Record), so let's try to get a look at the MBR.

Please try the following: You will need a USB drive/flashdrive and a new blank writable CD.

:step1: Please do the following on a working computer:
  • Download GETxPUD.exe to the Desktop.
  • Run GETxPUD.exe
    A new folder will appear on the desktop.
  • Open the GETxPUD folder and click on get&burn.bat
  • The program will download xpud_0.9.2.iso, and when finished will open BurnCDCC ready to burn the image.
    Please be patient: This could take awhile - download file size 63MB.
  • Click on Start and follow the prompts to burn the image to a CD.
You will use this CD to boot the ailing computer from.

:step2: Boot the ailing computer with the xPUD CD.
  • (You may have to configure the Boot Menu or BIOS Setup Menu to boot first from the optical/CD/DVD drive.)
    A Welcome to xPUD screen will appear.
  • Click on File.
  • Expand the mnt icon on the left (click on the little arrow beside the icon).
    • sda1, sda2 etc. ...usually correspond to your HDD partitions
    • sdb1, sdc1 is likely to correspond to a USB flashdrive, external USB hard drive etc.
  • Click on the folder that represents your USB drive (sdb1 ?).
  • Click Tool on the top menu, and choose Open Terminal.
  • Type the following at the hash prompt:

    dd if=/dev/sda of=mbr.bin bs=512 count=1

    • Note: Leave a space between the following:
      • dd ... the executable application used to create the backup
      • if=/dev/sda ... the device the backup is created from (the hard drive when only one HDD exists)
      • of=mbr.bin ... 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 ... 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 the <ENTER> key.
    After it has finished a file will be located on your USB drive named mbr.bin.
  • Go to Home > Power Off > Turn Off and remove the flashdrive as the system shuts down.

:step3: On the working computer:
  • Insert the USB drive, and navigate to the file mbr.bin
  • Zip-up the mbr.bin file:
    • Right-click on the file and choose Send to .. > Compressed (zipped) Folder.
      A zipped folder will appear in the same location as the mbr.bin file.
  • Please attach the zipped file to your next reply.
    This will allow the MasterBootRecord of your hard drive to be checked to see whether or not it is infected &/or damaged.
