  2. 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.

    Converting a MBR disk to a GPT disk

    I would put Windows on Disk 2. There is plenty of space. If you want to start with a clean slate then you should do this:

    • Disconnect disks 0 and 1.
    • Boot the machine with your installation medium.
    • Launch diskpart.
    • Select disk 0 (it was disk 2 before).
    • clean.
    • Reboot with your installation medium.
    • Install Windows.
    • When it runs nicely, connect the other disks and tell the BIOS which is the primary disk to boot from.
    Since disk 2 is only 232 GBytes you will not need UEFI / GPT. After Windows is installed you can convert the 3 TByte disk to GPT.
