I recently asked a question on here, and thought I had it working... Here is a link to it.

Windows XP Installation problems

So basically I'm having trouble getting XP installed. To sum it up, a computer I have had a boot sector virus, and I used Darik's Nuke and Boot to wipe the hard drive clean.

So the hard drive has nothing on it. I had to try and install Windows through a DOS prompt, because for some reason it won't read it off the DVD. The UBCD is able to look at the files located on the DVD I have in, but I can't boot from it for some reason. So I extracted it to a USB drive, booted to DOS and started the setup process.

Here's the weird thing with DOS... It can only find the C: drive. The C: drive in DOS is the flash drive that I have in, running DOS. I can't find the hard drive anywhere!

So anyways, after starting the setup process, it copied the files over to the "hard drive" (which took 16 hours because the version of DOS I ran couldn't run smartdrv.exe), and it said the computer had to reboot. So I let it reboot, and it stopped and said there is no boot device. So I popped in UBCD that I have installed on a flash drive, and I discovered that it had copied the Windows files over to the flash drive and not the hard drive. It never asked where it should extract the files...

So I toyed around with UBCD, ran a memory test on the hard drive to make sure it was fine, and it came out clean.

So I'm stuck now. How can I get this installed?

Writing this, I came up with an idea. If I copy the DOS startup files over to the hard drive, would I be able to start DOS from it? If so, I believe that could fix my problems.

Any help is greatly appreciated, because I am running out of ideas and am at my wits end with this computer.
