    That is what I'm using UEFI.
    In Disk Management, right click in the Disk number box, click Properties, click Volumes tab and note what it says. If the Partition style says "GUID Partition Table (GPT) then you are using UEFI and you should be able to simply right click that unallocated box and create a usable partition. If it says MBR then as stated, you've run into the 2.2TB limit and will have to set the BIOS to UEFI and either reinstall Windows (the easy way) making sure you've backed up your data, or go with option two as posted by Megahertz.

    Please post the image for us to see. Also what actually happens when you right click inside that unallocated box. Is there an option to create a "New Simple Volume"?

    From Disk manager image on post #1, there is no EFI Fat32 100M partition. It's for sure a Legacy - MBR disk.

    And also the System Reserved partition is marked as active. You can't have active partitions on a GPT disk, therefore the drive MUST be MBR.

    You guys are a lot smarter than me when it comes to fixing drive issues so I'm not countering anything. I'm simply going by what the OP posted in reply to this...

    Mbr cant have a boot partition larger that 2tb hard drive. U can install windows in uefi mode to have larger boot partition.

    Do I believe the OP is using GPT? No, based on the posts by both Bree and Megahertz; but we need to see what the OP thinks he sees. That said, you guys picked up clues in the Disk Management image I overlooked. It's why I'm also here to learn. And will continue to post and probe.

    Peace:)
