Hello Everyone,

My computer has a problem and when I turn it on, it loads to a black screen and then goes to a flashing underscore. I have tried using the F keys to boot in safe mode, but not even that works. The only thing it gives me is "Select from boot drives" and gives me three options. Floppy, Disc and HD. But still nothing works. Same flashing underscore.

System I have is: Win XP Pro, SP3, 32 Bit.

Thanks in advance for any help.

What is new or different since the last time everything worked properly (ie, new hw, new sw, virus, error, etc)?

I had installed a program towards the afternoon, and everything was fine and then before I went to sleep I did a malwarebytes scan and when it was done it came up with a trojan (dont remember clearly but I remember seeing a bunch of numbers when MB deleted it) had been found so I cleaned and restarted the computer and thats when it happened. I also tried to do a win xp boot cd that I got from an rc image and when I go to recovery it prompts me for an admin password and I tried my old password and that doesnt work and I also tried with no password and that does not work either. It says 3 attempts have been made, press enter to restart the computer. I hope this helps.

If you'd mentioned the trojan in the first post it would have been helpful. I suggest you post in the malware section of this site.

Sorry about that Allan and Ill go ahead and do that. If I could I would but I cant even log into my computer, the boot logo does not come up... thanks for the quick reply. All it does it go into a black screen and then I see a flashing underscore, and thats all it does.

Something similar to this topic I found.

Hello, to avoid confusion I have merged your topics.

Try this please. You will need a USB drive.

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.
  • Remove the USB & CD and insert it in the sick computer
  • Boot the Sick computer with the CD you just burned
  • The computer must be set to boot from the CD
  • Gently tap F12 and choose to boot from the CD
  • 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 ?)
  • Press Tool at the top
  • Choose Open Terminal
  • Type the following and press enter:

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

  • Press Enter
  • After it has finished a file will be located on your USB drive named mbr.bin
  • Remove the USB drive and insert it back in your working computer and navigate to mbr.bin, zip it up and attach it to your next reply.

This will allow me to have a look at the MasterBootRecord of your drive and see if it is infected.

regards, Elise

Hello,

And thank you OB.

Elise025, I have downloaded what you requested and burned the image to a cd. I have inserted the burnt disc and usb to the sick computer and I select to boot from disc. The xPUD comes and I chose English for the language and then it loads by itself. This is what I see on the screen:

Fatal Server error:
no screens found

Please consult the The X.org Foundation support at http:wiki.x.org for help. Please also check the log file at "var/log/Xorg.0.log" for additional information.

Can you try to boot from it once again? If you get the same error, most likely you have a video card or related component that is not supported by xPUD. In that case create a Ubuntu Live CD.

regards, Elise
