According to my experience, you failed to convert your disk from MBR to GPT for some reason, so the partition style of the system disk is still MBR. In this case, you only need to convert the disk from MBR to GPT again with the proper operation. However, before jumping into the conversion process for the second time, you need to run CHKDSK /F Command to check the hard drive to verify the file's integrity. CHKDSK stands for check disk and is a system tool that can scan your whole drive to find and repair the error. Find more details in the below article:

If there is no integrity issue on the hard drive, you can begin to convert the HDD from MBR to GPT. You can still use Diskpart to complete the conversion. However, using cmd takes much time, and improper operation can cause errors, which leaves you to find better alternatives. To successfully convert MBR to GPT, I highly recommend you try the third-party converter tool, EaseUS Partition Master, it can meet all your requirements for the partition. With this handy and user-friendly tool, you can convert MBR to GPT with a few clicks.
