GPT Reverting back to MBR

[lTyll]

Hey everyone,

I'm trying to install W7 Ultimate 64bit edition with my 4TB hard drive, but everytime I install W7 it comes up only with 2TB.

The steps I tried were

Before installation Shift+10 - diskpart - select disk 0 - clean - convert gpt

It all goes successful, but when It finishes it turns back to MBR

I'm installing through a USB and starting it in bios in UEFI mode.

Thanks in advance for any help

There are a few differences doing a UEFI Windows 7 install, look at the tutorial HERE.
