make a dos boot disk, preferably windows 98. restart your computer, go into the bios and set your floppy drive to your first boot device, restart again, when you get to the a:\ type fdisk, hit enter and it will ask if you want to enable large disk support, select Y and hit enter, if you're on NTFS partitions it will ask something else that i never bothered reading lol, i put y in and hit enter, then just follow the onscreen instructions and if you have 2 hard drives make sure you select the correct drive(option 5 on the main menu)
