win2k/ubuntu dual boot problem

I HAD a desktop that was a 600mHz p3 (coppermine) win2k/Ubuntu machine. recently i got my hands on a better 1.70gHz 500mb DDR ram machine that had no hard drive or graphics card. Basically i just took the graphics card and hard drive out of the 600mHz machine and put them into the newer better hardware setup. Now i know that MS operating systems are chipset specific, that is if i change the intel chipset, i have to re-install the OS, Ubuntu is not so much and boots and runs fine.

The PROBLEM is that when i pop in the windows installer disc, nothing happens, i see a black screen with cursor, then the list of OS to choose. I get no view of the bios and cant configure it to boot to cd. Its driving me nuts as all i WANT to do is to delete the c:/ partition and reinstall windows onto, leaving the other (ubuntu ext3, fat32, and swap partitions) partitions as they are as they work fine on the new/upgraded chipset. What is the easiest way to delete the current MS partition and re-install windows in its place, again, without wiping hte entire hard drive and start the partitioning/hdd formatting process all over again. Thanks to anyone in advance in help of this...

 

will the computer POST and let you into the Bios if you take the hard drive out? if so, take it out then set the bios to boot to cd then put the hd back in.

good luck
