I have a EP43-DS3L Gigabyte mainboard, with an Intel Core 2 Duo E8400 CPU. I just purchased a 3TB HDD, its currently my main drive as removed the 500GB one. I wish to convert my 3TB HDD to GPT so that I can use the full 3TB and not just 2048GB, but in order to have a GPT HDD as my main drive I believe I need to be using UEFI and not BIOS? Is this correct, and does anybody know if my mainboard can support UEFI?
