Considerations before converting MBR to GPT

Do you know the differences between MBR and GPT partitions? When we talk about MBR and GPT, we are referring to partition tables, being MBR the most important to use for many years. In any case, in recent years, due to the increase in the size of unit di storage, it was necessary to implement a new technology, such as GPT.



GPT is much more functional, is capable of working with larger partitions and offers multiple advantages over MBR. In any case, if you have a hard drive with MBR partitions, you will need to convert them to GPT.

The conversion process is simple and there are multiple options with which to do it, even so, we highly recommend that you make a backup or backup of the hard drive we want to convert.

  3. Once the command console appears on the screen, you will need to type the following: mbr2gpt / convert / disk: disk number / allowfullOS. Remember to replace "Disk number" with the number assigned to your storage drive, this information can be viewed in the hard drives section of Windows.
  4. At the end of this procedure, the conversion of the MBR to GPT file should begin. When the process is complete, the file system of the selected drive should already have been successfully converted.


MiniTool Partition Wizard

MiniTool Partition Wizard is one of the best programs to partition hard drives with which you can keep control of our storage drives. Likewise, the application is fully functional to convert hard drives from the MBR format to GPT format.

To perform stationing using the application, the first thing to do is download the program from the partitionwizard website. Note that to use MBR to GPT conversion, you will need to create a bootable drive with the MiniTool Partition Wizard program, this feature is paid.

      3. Restart your computer and boot from the USB drive you prepared in advance.
      4. The MiniTool Partition Wizard program and all storage drives on your computer should appear on the screen. Select the drive you want to convert MBR to GPT and right click on it, here you need to select the option «Converti disco MBR in disco GPT».
