Okay, this should be easy but it's got me a bit confused. I was looking to upgrade from a 1TB drive to a 3TB drive for my OS (using Win8.1.) Everything I read from Msft said to use a GPT drive instead of MBR for drives greater than 2TB so I tried to comply but failed at every turn.
Things I tried..
1) Clone my MBR 1TB drive to 3TB drive. Ended up with a bootable 3TB drive but I couldn't access anything past 2TB even to format.
2) convert 3TB drive to GPT using diskpart (select, clean, convert to GPT) and then install using Legacy+UEFI boot setting in the BIOS. Then reboot and install Windows from DVD. Windows complained that I didn't have a drive that it could install to.
3) using the same drive setup as in #2 and changing the BIOS to be set to UEFI boot. This ended up with the same complaint from Windows that I didn't have a drive that I could install Windows on.
So my question is how do you install Windows on a GPT drive? It shouldn't be hard but I've failed to do it so far. The only thing I can use the 3TB drive for (and access all 3TB) is as GPT data drive. The drive isn't going to waste but it's not what I originally intended to use it for.
This is with a MSI Z97 PC Mate MB with the latest BIOS.
