Does windows, running on latest Apple computers, see boot disk partitioned as MBR or GPT?


From my understanding, the newest apple computers boot windows in EFI mode. Traditionally, Windows has seen the boot disk as an MBR partitioned disk. In fact, the boot disk (i.e. /dev/disk0) has aways been partitioned as a GPT disk. I would like confirm there has been a change.


To be specific, open a Command Prompt as a Administrator and enter the following:



diskpart
list disk
exit


What I am looking for a * in the Gpt column for Disk 0. An example, using an older apple (iMac/20 inch/Mid 2007), is shown below. Example of diskpart command


In the above illustration, Disk 0 is the internal hard disk partitioned as a GPT disk. To Windows it appears as an MBR partitioned disk, indicated by the absence of the * in the Gpt column. Disk 1 is a gpt partitioned USB thumb drive containing a single NTFS partition.


If you show a * in the Gpt column for Disk 0, could you report back the "model identifier" or "model/screen size/year" of your apple computer. It may also be useful to include the version of Windows and OS X you are using. Apple recommends a standard where there is one partition for OS X and a second Boot Camp partition for Windows. If you are using a nonstandard partitioning scheme, try to indicate how you differed.
