When my computer first came it was in GPT format. after which i wanted to re install the windows 7 but it asked for mbr format so i Converted it succesfully to mbr through easeus partition . after i installed the windows i wanted to convert it back to gpt which was succesful but a blinking underscore is coming.

  3. convert MBR to GPT disk

    convert mbr to gpt

    There is a way to convert mbr to gpt without data loss. clean command deletes all datas inside the disk, so dont use this command

    boot with windows dvd , and get into command prompt

    type diskpart , find the disk number , which is need to convert mbr to gpt

    say disk number is 0

    exit diskpart

    type below command in command prompt

    mbr2gpt /convert /disk:0

    wait for some minutes to complete , once you get commpleted successfuly means, exit and close ,

    shutdown the pc , remove windows dvd

    important

    After the disk has been converted to GPT partition style, the firmware must be reconfigured to boot in UEFI mode.


    Make sure that your device supports UEFI before attempting to convert the disk.

    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.
