00:00You can also check the partition style using Diskpart.
00:02Open command Prompt or Windows Terminal as administrator.
00:06Type Diskpart, then type List Disk.
00:10Windows will display your disks.
00:12Look at the GPT column.
00:14If a disk has an asterisk in the GPT column, that disk uses GPT.
00:18If there is no asterisk, it is generally using MBR.
00:22Remember that Diskpart contains commands that can modify or erase disks.
00:26So use commands such as Clean or Convert only when you understand their consequences.
