To convert back to MBR, open administrative Command Prompt and type these commands and press Enter key after each:

diskpart

list disk

select # Replace # with exact disk number in your case.

clean

convert mbr

exit

Close Command Prompt. Note, this method will result in loss of data in conversion.

Let us know if this helps!

How can I change from MBR to GPT and vice versa from GPT to MBR in Windows 10 Home

Usually, MBR and BIOS (MBR + BIOS), and GPT and UEFI (GPT + UEFI) go hand in hand. That's to say, if a Windows computer that uses UEFI, it will only support GPT. if your motherboard supports BIOS, go for MBR.

As for converting MBR to GPT and vice versa, you can enter Disk Management, and right click the disk to choose "Convert to GPT Disk" or "Convert to MBR Disk" to finish the conversion. BUT this method only supports convert an empty
disk (no volumes) to MBR or GPT. Deleting volumes/partitions on the disk will cause data loss. In order to convert disk between MBR and GPT without data loss, you need to first back up everything important, or turn to a 3rd party

free MBR to GPT converter, which allows you to directly convert a disk containing volumes/partitions to MBR or GPT.
