If the F8 key works, try Last Known Good Configuration :

  • Power on the compute and tap the "F8 key" continuously until you get the "Windows Advanced Options Menu."
  • Use your arrow keys to move down to "Last Known Good Configuration" then press the <Enter> key.
  • Reboot the computer.


If no luck, and you can get to the "Windows Advanced Options Menu," then try Safe Mode and perform a system restore to just before the problem started.

Regards,
Brooks

... it showed the hp logo then just went to black screen with blinking cursor I ran hdd test from bios and everything passed.

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.

No problem this end with the time delay.

The MBR partition table appears to have suffered some damage.
  • The system is set to boot from the first of two partitions but the the first partition is not valid.
    • That explains why Windows will not boot from the hard drive!
  • The second partition appears to be valid and 37GB in size.
Virustotal returns no hits on mbr.bin so it is not seen as a known malware infection (virustotal.com result).

I will consult with colleagues on the situation and get back to you when we can figure out the best approach to restoring things to normal.

I think there was a good chance malware was involved in rendering your system unbootable.

Please sit tight and be patient for now:
  • I have requested that an experienced helper who specialises in malware-related un-bootable computers respond to your topic.
  • A suitably experienced helper will respond when they are available.

Seems like you have a similar issue to me 111. I tried restoring using boot disc and couldn't get the password it asks for at restore. IT guy at my work says probably need to contact HP tech support to get it, and might need to pay.
