Create Drive/Delete Partition on 4tb Drive Problems

[Jpellitt]

Hi - quick thumbnail of my journey:
- replaced HD with 4Tb drive
- found out Win 7 32-bit won't see all of it (or recognize extra RAM)
- reinstalled Win 7 64-bit
- 2tb still "unallocated space" - all menu options greyed out (can't make a drive of it) - at least RAM being recognized now.

Every solution I've researched seems so easy! And doesn't work! Any help greatly appreciated!

You need UEFI BIOS, and GPT partitioning, if you want to boot off that drive.

What if I don't necessarily want to BOOT off the drive...just have it available for storage? I may be mixing up the terms "drive" "volume" and "partition"....maybe I can ask it this way: if I want to use the 4tb AT ALL, in any capacity, do I need to change the BIOS and partitioning? Or is there a way to use that unallocated space without those changes? I am afraid I know the answer....but....?
