I have a Dell R710 Server with H700 raid controller installed.  I have a 1Tb Raid 1 for the OS and a 2Tb Raid 1 and a 3Tb Raid 1 for Data.  I configured the Raid in the H700 Raid controller and everything looks great.  However when I install the 2012 R2 OS I can only use 2 Tb on the 3Tb Raid array.  There is no UEFI option in the bios configuration.  How do I enable UEFI on the Dell R710?

If you enable UEFI at this point, you are looking at a reinstall of Windows, BUT you also don't need it: Go into Disk Management, select disk 2 (or whichever is the 3TB disk), and Convert to GPT. THEN you can format and use all 3TB. Backup any data that is on that volume first though, as it will be erased when you do the conversion.

I tried that but it doesn't let me.  Everything is grayed out.  I tried Diskpart but it won't let me clean it because it says its a system disk (which it isn't).  I would love that have this work but I'm ready to do a clean install of windows if necessary to enable UEFI.

Changing to UEFI won't help though.

Try going into OpenManage (OMSA), Virtual Drives, and deleting that RAID 1, then reboot. Then configure the RAID 1 from OMSA ... you should be prompted in Disk Management to Initialize it, where you can select GPT.

If when you reboot the OS doesn't boot, boot to a Windows disk and do a Startup Repair.
