Difference between GPT and MBR GPT (or GUID Partition Table) is the updated version of the MBR table scheme that’s available on computers with UEFI/EFI installed (not BIOS). GPT may also be used on some computers that have BIOS installed and not UEFI/EFI. These type of disks have the following advantages: 

It can have to 128 partitions vs. 4 partitions on a MBR disk



A single partition can have up to 256TB vs. 2TB maximum allowed space on a MBR disk

GPT disks can be read by the following Windows versions: 

Windows XP 64-bit



Windows Vista



Windows 7



Windows 8



Windows Server 2003 and Server 2008

These disks can also be used to boot Windows from, but only the 64-bit Windows versions will boot from GPT: Windows 8, Windows 8.1, Windows 7, Windows Vista and Windows Server editions.

Note that you can boot Windows from GPT only if your computer has UEFI/EFI installed. MBR disks are supported by all Windows versions. Removable disks, such as USB drives, can’t be converted to GPT. These removable disks are set as a MBR.

Convert GPT to MBR using Disk Management To convert a GPT disk to MBR using the Disk Management utility, follow these instructions. These instructions apply for these Windows versions: Windows Vista, Windows 7 and Windows 8 or 8.1. Disk Management is installed by default and it’s available on your Windows computer. 1. Boot into your Windows (Vista, 7 or 8) 2. Click Start 3. Go to Control Panel 4. Click Administrative Tools 5. Click Computer Management 6. On the left menu, click Storage > Disk Management

7. Right-click on each partition from the disk you want to convert from GPT. You must delete all partitions from the disk before you begin the converting process from GPT. To do so, click Delete Volume on each partition until the entire disk has unallocated space.

8. Right-click on the disk and click Convert to MBR Disk 9. Once the process is done, you can now create partitions on the new disk as you wish 10. Close Disk Management when done

Convert GPT to MBR using Command Prompt If you’re not able to boot into Windows (Vista, 7 or 8) to run Disk Management and perform the converting process, you can also use Command Prompt (either from the original installation disc/USB or via Command Prompt from Easy Recovery Essentials). You can perform these steps either by booting into Windows and running Command Prompt from Start > Run > cmd or by using the original installation disc to open Command Prompt, if you can’t access Windows. To do so, follow these steps: 1. Insert the Windows installation disc and restart your computer 2. Boot from the disc by pressing any key at the “Press any key” screen 3. Go to System Recovery Options
