No boot disk available -
My Dell GX240 with Win 2000 was working great,it is a Pentium 4 - 1.5 ghz and 512 Sdram. I loaded Microsoft Vista Beta 2 on a similar computer, it was very slow. I moved that hard drive to my GX240, it wouldn't boot up. So I put the old GX240 hard drive back in, now it won't boot up. In the bios "boot sequence" the floppy, cdrom, hard disk do not show up, instead a 1.n, 2.n, 3.n, are where they should be. In the Primary O and Secondary O they are setup and set to auto, plus my Diskette Drive A: is where it should be. I have disconnected and checked all wires and cables several times. I've put in different hard drive, floppy, cdrom, and sdram memory. My guess is "Vista" changed some settings and they need to be changed back for my computer to start working again. Help!
