GPT to MBR: Can A GPT Disk Be Converted to MBR?

Read the full post: GPT vs. MBR

While setting up a new disk on Windows 10 or 8.1 and you'll be asked whether you want to use MBR or GPT. As we know, MBR and GPT are two different ways of storing partitioning information, and each has its advantages and disadvantages.

In general, GPT is seen as the future which is meant to improve upon the limitations of MBR including the storage limitations. However, many users still prefer MBR over GPT because it is still the most compatible and is still necessary in some cases as listed here:

  • Choose MBR as a system disk if you have a 32-bit Windows to install.
  • Choose MBR for system disk if you're still using the very old Windows OS.
  • If you are running Windows XP or older systems, MBR is the only choice for system disk even if it is a 64-bit system.
  • Receive the error message "Windows cannot be installed to this disk. The selected disk is of the GPT partition style" during Windows installation.

Technically, there is no answer to "Is GPT or MBR better" because the right partition style is always the best. And if you currently use GPT, and you'll need to change GPT to MBR by choosing one of the three solutions in the next part.

To ensure that you convert GPT to MBR without affecting data inside, EaseUS Partition Master is known as the top-choice GPT to MBR converter that you can't miss.
