Cannot convert GPT to MBR.

Hi Michael,



I suggest you to follow the below steps and check if it helps.

This method you have to backup all your data and delete all partitions and volumes. Then use the
DISKPART command.

• Open command prompt and type in DISKPART and press Enter
• Then type in list disk (Note down the number of disk you want to convert to GPT)
• Then type in select disk number of disk
• Finally type in convert gpt.

Hope the information helps. Do reply if you need further assistance.

 

Disk Management

Hi Keith,

Thanks for providing the detail that was requested previously. Since the disk management screen that you saw is showing greyed out options, we suggest that you follow the steps below to change the partition type of your internal drive:

• Open Disk Management then right click the partition on the disk you want to covert and select Delete Volume.
• Once you complete the process you will see the whole disk shown as two separate unallocated spaces. Right-click the disk and select Convert to GPT disk.

After the conversion, you will be able to use the whole disk and then you can create new separate partitions.

We look forward to your response to our queries.
