If the primary partition of the drive is FAT32, NT will not be able to install, since it needs to have its boot loader there. If you enable FAT32 and want to create a FAT12 or FAT16 partition, you'll need a third-party disk tool like PowerQuest's PartitionMagic to manage the partitioning and formatting.

If you do not enable FAT32, or you use Partition Magic to handle partitioning and formatting and you make the primary partition (drive C: under Win95) FAT16, you'll be able to install NT in a dual boot environment without a third-party boot manager like System Commander, or the Boot Manager that comes with Partition Magic. Win95 can create FAT16 partitions up to 2GB in size.

FAT16 will not support primary partitions >2GB under Win95/98. Logical drives allocated from an extended partition using Partition Magic can be FAT32 (unusable from NT without third-party software), FAT16 with the same 2GB/logical drive limit usable from both NT and Win95, and NTFS (unavailable to Win95 without software drivers, and the only driver I'm aware of for DOS and Win95 is a read-only utility.)

I'd get a third party boot manager like System Commander or the Boot Manager in PowerQuest's Partition Magic if I had to do this. My experience is that dual boot 95/NT systems are bad news in the long run; any application that must be used in both environments must be installed twice (once under each OS, since the two OS do not share the registry, and in many cases different drivers and .DLLs are used for Win9x and NT.
