how do I know if my HD is MBR or GPT?

post #1 of 6
Thread Starter 
The reason I'm asking this question is because as soon as my PC arrives I'll be doing a UEFI installation of Windows 7. If done correctly the HD should be in GPT, so I would like to know how to indentify it.
Thanks. smile.gif

Hard drives don't come with an MBR out of the box, it's installed by the OS during installation in order to make the drive bootable. Since Windows 7 can be booted from a UEFI machine, such as an Apple Mac, then I assume Windows 7 has the ability to create a GPT boot partition as part of the installation routine.

The hard drive itself won't care one way or the other.

You don't need (or want) a GPT partition unless the drive is larger than 2TB.

I know Windows 7 can make a GPT HD and requires EFI to boot. What I want to know is, after I've installed Windows 7 in UEFI mode, how can I check if my HD is in GPT or MBR?

I know that, but I want to make it in GPT anyway.

Please answer my question, thanks. smile.gif

How about a disk partitioning utility? I don't run Windows, so I'm not familiar with the various products available. Partition Magic, maybe?
