The poster apparently wants to install 98SE and -other OS- (dual-boot) has no boot floppy to allow for partitioning. In addition, the 98SE is apparently an OEM Bootable, which by default will want to create a partition occupying the whole Physical Disk (runs OEMSETUP).You could just go ahead and install, then defrag, then use a gParted CD (free Linux-based) to re-partition (shrink 98SE then create new). If you have a Floppy, go to BootDisks-dot-com and download an appropriate boot floppy image. Please explain your intentions/objective more clearly for more accurate assistance. Hi Submix8c so i can just install 98se and then make C and D partition with a gParted bootable CD? Just what it means ''shrink 98SE then create new''? The disk is 80Giga and i need to make two 40giga partition.
