... I get an unresponsive blinking white ... underscore on a black screen.
It is likely that the MBR (Master Boot Record) on the hard drive has been adversely affected.
Please try the following: You will need a USB drive/flashdrive and a new blank writable CD. Please do the following on a working computer:
You will use this CD to boot the ailing computer from. Boot the ailing computer with the xPUD CD.
- 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.
On the working computer:
- (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.
- 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.
