Question

Why I cannot initialize disk to MBR in server 2012 with the new Server Manager ? just GPT is allowed?

Answer 1

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

Answer 2

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.
