I'm a newbele mysef... but i know what i'm doing... kind of... if that makes sence...
Anyways, sounds to me like either you've downloaded the 64bit version (when i ran a search on suse.com it came up with 64bit stuffs) or there's something wrong with your HDD.
Do you really still want MSWin? if you don't burn your stuff to cd, get a 98 boot floppy and run FDisk and delete the partitions... thats what i would do anyway... but don't take my work on it
hope i've helped a little
