The ripper is a oldy but goody. I had a friend who was infected with it. He reinstalled his OS 3 times before figuring out he had to recreate his MBR. Also, I believe he had to do a low level format of the HD. I can't imagine someone not having a boot disk. You may want to check and see if one came with your PC. Seems like you could get to a library, or a friends PC, to create a boot floppy, if you can't find one.
