I bought a 3TB hard drive for my gf and did a fresh install of Windows 7. When I was creating the first partition the Win7 install auto created two more volumes, both labeled as Unalloated. I thought nothing of it as I figured I would be able to merge/create my second partion with the remaining space once Windows was up and running. However, to my dimay I can not create a partition on one of those random Unallocated volumes. I've tried to delete all partition but the one that my OS is running on and I've tried to create two then merger but when I right-click on the second (first one works) volume the option t create a simple volume is greyed out.
This is me being able to create a partition on the first:
This is the second, as you can see the "new simple volume" is greyed out:
Any help would be greatly appreciated! My goal is to just have two partitions, one for the OS and the other for random files.
P.S. Oh and a side note, I tried using EaseUS Partition Master 9.2.1 and that did not help. I was still not able to create a partition or merge the two volumes together.
I've had that happen before and it confused me as well. I think its something to do with the windows disk management. It may let you create one there after you create a new volume on the one before it. That or try another free partitioning program easeus is pretty simple
Your problem is that, your disk must be initialized as MBR disk, as we know MBR disk could only support 2TB storage disk, if you want to use the disk which is larger than 2TB, you must initialize it into GPT disk.
Here you need something to note:
First, if you want to boot system from a GPT disk, your motherboard must support UEFI mode. The bios could not support boot from GPT disk.
Second, if you want to convert MBR to GPT disk, you need delete all the partitions first, then re-initialize your disk. Or you need to use other software (as I know there's no free software could do this).
