Nowadays, the tendency of GPT disk becomes irreversible owing to its excellent performance. But how much do you know about certain disk type? In this article, we would like to introduce the concept GPT and its superiorities over MBR. Moreover, users needing ways to convert MBR to GUID Partition Table in Windows 2008 Server can gain satisfying answers here.
GPT, short for GUID Partition Table was introduced as a part of the Unified Extensible Firmware Interface (UEFI), and computer users can only boot from a GPT disk if computer motherboard has an enabled UEFI BIOS. In terms of MBR, it is the acronym of Master Boot Record. The following is the differences existing between MBR disk and GPT disk:
1. Availability in Windows operating systems
MBR disks are supported by all Windows operating systems, while GPT disks are only supported by Windows server 2003 SP1 +, XP 64-bit, Vista, Windows 7, Windows Server 2008, Windows 8, and above.
2. Type of partition table
MBR disks use the standard BIOS partition table, while GPT disks use UEFI.
3. Partition amount and types
In MBR disks, users can only create 4 Primary partitions or 3 Primary partitions and 1 Extended partition with up to 128 logical volumes in the extended partition. However, GPT disks support up to 128 Primary partitions. MBR disks support up to 2 TB per single partition, while GPT disks support 256 TB per single partition.
In some cases, computer users may need to perform disk conversion so as to make use of inaccessible disk space when the disk is configured as MBR. Well then, how to convert disk between MBR to GPT?
Solution 1. Using diskpart command line
Using Windows Server 2008 diskpart exe, users can realize some basic disk and partition management operations including create volume, delete volume, extend volume, shrink volume and convert MBR to GPT. But functional limitations and defects of those features can not be ignored. For instance, the “extend volume” command works only when there is unallocated space right behind target NTFS partition. Moreover, users have to carry out series of operations via typing complicated commands, which increase the rate of misoperation. As a result, it is of low recommendation.
Solution 2. Server partitioning software
Since the Windows built-in disk managers: diskpart command line and Disk Management tools fail to manage disk and partition well, professional server partition software becomes a must, and MiniTool Partition Wizard Server Edition owning high partitioning capability is highly recommended for users. To give users a better understanding, we would like to introduce how to convert Server 2008 MBR disk to GPT disk.
Users just need to take the following operational steps to fulfill disk conversion in Windows Server 2008.
Step 1. Download the powerful server partition manager and then install it to computer. After that, launch the software to open its main interface.
Step 2. In the main interface of the software, choose the target disk and click “Convert MBR Disk to GPT Disk” from “Operations” area.
Step 3. Backing to main interface of the software, users can view that the chosen MBR disk has been converted to GPT, and all relevant operational steps are listed out in “Operations Pending” area. To apply MBR disk conversion effect to computer, users need to click “Apply” button in the upper left corner.
The whole operation to convert MBR to GPT in Windows Server 2008 is explained as above. If users need more detailed information, please visit the quick link here.
