MBR VS GPT for Windows Server 2016
Currently, when building servers, users prefer drives with a capacity greater than 2TBs. As we all know, any disk space beyond 2TB will be unusable if the drive has been formatted in the Master Boot Record (MBR) style. Therefore, if you are going to build a new server using Windows Server 2016 then it is recommended that you choose the GUID Partition Table (GPT) partition style, which uses the Unified Extensible Firmware Interface (UEFI) boot mode.
Most new hardware uses the advanced UEFI by default rather than Legacy BIOS, however, the majority of older hardware will also include support for UEFI to. In order to check whether your hardware is compatible you should look on the manufacturers website. So, if you want to make full use of your drives larger than 2TBs then convert it from MBR to GPT in Windows Server 2016.
Convert to MBR/GPT with Windows 2016 Disk Management
Windows Disk Management is only able to convert disks between MBR and GPT when the disk is empty and doesn’t contain any partitions or volumes. This means that if you want to use Disk Manager to convert your disk then you will need to back up all your data to external storage. You can follow the steps below to convert a disk between MBR and GPT with Disk Management:
1. Right click the Start button to open up the Quick Access Menu, in the Quick Access Menu select Disk Management.
2. Right click on each partition on the disk that needs to be converted and select Delete Volume to clean the disk.
3. If you want to convert MBR to GPT, right click on the disk, and select “Convert to
If it is a GPT disk that you want to convert to MBR, then the option available will be “Convert to MBR Disk”.
After a short wait, the disk will be converted to GPT (or vice versa), you will then be able to repartition the hard drive. If you want to convert an MBR boot disk to GPT then you will be unable to use Windows Disk Management as you can’t delete the boot partition. As a workaround, you can boot your server from a Windows Server installation disc and press Shift +F10 to open the DiskPart utility. In DiskPart you should enter the below commands in command prompt to convert the disk to GPT:
Note: Both methods for converting GPT will cause data loss, so make sure you backup your data beforehand. Fortunately, there is free software that you can use to convert between MBR to GPT without losing data.
