    How big is the drive/volume? If greater then 2TB, then MBR isn't really much of an option. – Zoredache Feb 10 '14 at 07:52
  • Yeah, I am aware MBR doesn't support disk greater than 2TB. But what concerns me is that though the disk is only 100GB, I cannot initialize it to MBR format in the new Server Management in 2012... I think MBR will be eliminated. – Atom Feb 11 '14 at 08:08
  • I've seen this, too; looks like they are just silently deprecating MBR. Oh, well, I just don't use that godawfully slow Server Manager anyway... – Massimo May 27 '15 at 06:16

When in doubt, use PowerShell. In fact, probably better to just use PowerShell by default. Worst case, you should get an error message to indicate why you can't use MBR with this disk.

To initialize a disk as MBR, use the –PartitionStyle parameter. For example:

Initialize-Disk 4 –PartitionStyle MBR

You can launch the old/familiar Disk Management console by typing: diskmgmt.msc at the start - search/launch box, It should give you the option to select MBR during the disk initialization.
