Ensure - a: bios is OK for the drive size; b: that when you install NT you include the upadted atapi.sys - which enables NT to handle larger drives... That file/driver is part of sp4 and can also be downloaded as a separate entity. Either way it is installed during early part of NT installation.Remember too that during setup the max partition size that NT can create/format is 4Gig (be it fat16 or ntfs). If you want a larger (primary) then you preconfigue/preformat it in another NT system, and then return drive to its own PC - than carry on with NT install.
Likewise you can also install NT to a small (fat16) priary - make it around 200-250Meg; include (again) the sp4 atap.sys during setup. Then once NT installed (a bare bones installation... use NT disk Admin tools to configure/partition balance of drive as you wish - and format accordingly...)
This approach gives you a dual-boot NT/NT system - NT in two locations... You can retain or delete the version in the smallish Primary... Personally I'd retain it; allows a way in if the main installation goes pear-shaped...

installations section. (if the link still works) covers all aspects of this issue...
Also be aware that without the sp4 update... NT will not see beyond the 7.8/8Gig mark...
Also, it's not recommended to extend the Primary (via any method) beyond the 7.8/8Gig limit (if boot/system partition are one and the same); this because there is risk of boot-files moving beyond the 7.8/8Gig barrier - which 'could' happen.
