Question 4TB HDD installed, now only 2TB of space shown after Windows 10 installation

I've done a little digging and it looks like I need to make a switch with my Bios from Legacy to UEFI. Not sure I want to do this. I'm wondering if there would be any future problems with Windows 10 only recognizing 2TB of space on a 4TB HDD. The first thing that comes to mind is disk de-fragmenting. Seems like it would be an issue to run a defrag on partially recognized HDD.

Booting from the DVD matters not, unless it doesn't boot.

Got it, thanks again.

Egg-zactly.

Success, Windows re-installed and everything pretty much back to how it was, with 4TB of storage.
