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.
