For those who love computers and play with the computer a lot, converting the drive format is a very familiar task. Each different drive format has different advantages and strengths. For MBR drives (short for Master Boot Record) use the standard BIOS partition that is suitable for installing Windows GPT drives (short for GUID Partition Table) use the UEFI integrated Firmware interface. Speaking of advantages, GPT is much stronger when it comes to supporting users to create lots of partitions on each drive, if anyone is a service that needs a lot of storage, GPT is the perfect choice.

Converting the drive format from MBR to GPT does not have any difficulty because you can convert directly via CMD on your computer. Here's how to guide conversion.

  • Back up all data in case of bad circumstances.

    • Step 1: You press Windows + R to open the RUN window and enter DiskPart -> Enter .
