Convert GPT hard drive to MBR

The terms MBR and GPT are certainly a term for most users and are names for partition types . GPT is the short form of GUID (Globally Unique Identifier) and is based on the UEFI mode (Inified Extensible Firmware Interface) . Such a GPT drive can currently contain up to 128 partitions.

The abbreviation MBR means ” Master Boot Record “. An MBR drive, however, use the Legacy Bios mode and a maximum of 4 primary partitions can be created. You need an MBR drive, for example, if you want to make an internal or external hard drive bootable .

If, for example, you now have a hard drive that has been set up as a GPT drive and you want to convert it into an MBR drive , you should follow the following points:

ATTENTION: This process deletes all data on the data carrier!

First you open the disk management “diskmgmt.msc” . After right-clicking on the disk, you can see the disk properties and see that it is currently a GUID partition table (GPT) , as you can see below.

After that, the partition, in this case the volume Z:, must first be deleted . You can do this by right-clicking in the volume and partition area and then confirming ” Delete volume … “.

Delete volume

The partition will then be deleted and you can now select the following option with the right mouse button in the front disk area.

We have also shown this to you below.

The data medium is then converted to an MBR data medium . You can also check this again in the data carrier properties.

Master Boot Record (MBR)

Now the partition style shows “Master Boot Records (MBR)” and the conversion process is finished. Finally, create a new partition and you can use the MBR disk .
