Now, how do I install Windows NT 4.0?(my CD-ROM is a non-bootable CD-ROM)

Actually, the main problem is :

1) I've 2 hard drives.
2) One of these drives has Windows XP installed, and the other contains some useless folders and files etc.
3) When I boot into DOS-mode when the PC starts up, it seems to show only 1 drive : the one with Windows XP installed.
No matter what commands I type, the other drive doesn't seem to be detected or shown or listed!
4) In Windows mode, however, the second hard drive actually shows up!(in Windows Explorer)

And in this case, I wanna install NT 4.0 on my 2nd hard drive, but when I run the setup.exe on the CD-ROM manually, it keeps saying that NT 4.0 should not be installed on this current version of Windows.(which is XP)

Of course, the only way is to boot into the 2nd hard disk in DOS mode....but hey! NT 4.0 setup can't even run in DOS-mode!

Argh! This is crazy! Is there no way to install NT 4.0 on my 'vanishing' 2nd hard-drive?

And no...Virtual PC can't install NT 4.0 too, for some darn reason.(no NT boot disks)

Drats!
