I just used the EaseUS Partition software and coverted my 3TB HDD to GPT from MBR to get my full 3TB's of usage as I was only getting 1.99.

My OS is a fresh install of Windows 7 N on my SSD and everytime I reset my computer it goes straight to the UEFI BIOS of my Asus Maximus VII Hero MB, I've made the SSD the boot priority and disabled all other.

I'm not really sure what to do so could someone give me a little direction? Thank you.

EDIT: Running Windows 7 N (64-bit) installed via USB (Don't have a disk).
 
Hi

You dont say what version of Windows 32bit or 64 bit
but as you are not booting from 3TB HDD this is not critical

Assuming you have the Windows 7 DVD
with only the SSD connected boot from Win 7 DVD and do a repair of Startup files
which seem to be corrupted or were on 3TB HDD

Once you can boot up from SSD re connect 3TB HDD
