Su0013 hell (win98 First & Second Edition)

Would be very grateful to anyone who can get me out of SU0013 hell,
i.e. Windows 98 setup cannot continue cause of NTFS or other non-fat
partition hell (its wrong...it just THINKS its not a Fat or Fat32
partition (tried both!!!).

I cannot remember everything I have already tried, but will list as
many as come to mind, and after that include some specifics about my
system. Even if you can't offer specific solution, looking for
possible causes I have overlooked:

Already tried:

-Microsoft Knowledge Base
-Fat and Fat32
-deleting NTFS partition that resided on same disk
-reformating
-fdisking and reformatting
-disconnecting Promise Ultra 133 card
-switching hard disks
-shutting off and disabling various components
-uninstalling bootmagic
-installing from windows and from Dos
-disconnecting and disabling Zip drive (external)

System Components:

Intel 1.6 Ghz processor, 768Mb Rdram memory (yes, entry was made so
Windows thinks only 512Mb present), Mag LT565 monitor, Turtle Beach
Sound Card, 2 Western Digital Hard Drives and 1 Maxtor Hard Drive.

Any ideas appreciated, just please don;t be offended if I tell you
I've already tried something and forgot to mention it in original
post.

Thanks,
Larry
