Convert MBR Disk to GPT Disk

Winefly,
Well it was worth a try. Looks like you will need to use step 2 in OPTION TWO of this tutorial to convert the disk to GPT in a command prompt at boot. Afterwards, do a clean install of Windows 7 on it. Be sure to backup anything that you do not want to lose first though.

GPT Data Disk Confusion
At the start you say that you can still use a GPT disk for data even if your boot disk is a MBR. But is it still required to have an EFI BIOS in this setting? Or is the EFI BIOS only needed for booting from a GPT disk? Thanks.Last edited by XrayDoc88; 11 Oct 2011 at 12:37.

Hello XrayDoc, and welcome to Seven Forums.
A EFI BIOS would only be required if your were booting from a GPT disk. :)

GPT and RAID
This is a little off topic, but is there any advantage or reason to use GPT disks if you're building a RAID 5 array with five 2 TB hard drives? It seems like either way, you could still have a single huge partition, correct?

Oh, so if you were to use five 3 TB MBR drives in a RAID array, the array would only see five 2 TB drives?

Correct, unless you broke them down to smaller sizes in Disk Management, or used GPT to use over 2 TB.
