OK, I finally got a brain in my head. I'm doing now what I would do with a hardware issue - troubleshooting. I've downloaded the full version of VectorLinux, but I won't install it. If the install begins to succeed, I obviously have a faulty download of Kubuntu. However, if I get a similar or identical problem, I'll know that I am at fault. In that case - I'd have to rely on GX1_Man's more-than-merely-kind offer.
I have a hypothetical question about my hard drive and Linux/Windows. Let's say something goes terribly wrong and Windows crashes, forcing me to format that drive to access it. (Considering Windows' history, this isn't too far-fetched, though it's never happened to me) Even though Linux cannot read the files and open them, would it be possible for me to use Linux to copy the needed files/programs onto a special folder in the D: drive, format C:, and move the files back without damaging data?
[edit]Alright, now I know the culprit. It's me. I can't figure out how this is, but VectorLinux locked up too. Shouldn't it at least do something a few seconds after I hit the enter key? I'm going to try one more thing: I'm going to make two Kubuntu discs, and one of them will be extracted. That's the only thing I can think of now. If neither works, GX1_Man can expect a PM.[/edit]
