increasing size of NT4 boot partition

I’m trying to make the C boot drive larger on an NT4 server. The current drive is split into C and D, C being 1.2 Gig. FAT and D is 4 Gigs NTFS. I tried to use Ghost 2002 to migrate it to a 40 Gig. drive, but it wouldn’t boot afterward (using Ghost to increase the size of the boot partition to 4 gigs). I’m thinking maybe I can convert the boot partition to NTFS before the ghost & maybe it’ll go better. Has anyone tried this? Other suggestions?
