okay.. i started with NT4, and it said that I didn't have a hard drive "setup can not detect a mass storage device, make sure that the etc etc... " and the hard drive works fine and is hooked up, cause I'm running 98 off of it.. i got the second partition reserved for either of the NT's.. 4 or 2000 and I can't install either cause they both give me that message. I heard that NT4 won't recognize it cause it's ata 100 (diamond max hdd) but 2000 won't either (and I would have thought that it could). The other thing I heard is that you need to put it in an extended dos partition. That one doesn't make sense to me, cause I thought it had to be primary to be bootable.. ?? please help me.. I've been wrestling with this for a whole stupid week and it's killing me... <edit> the second partition that I have reserved for win2K or NT is ntfs, not fat32</edit>
