    MBR to GPT conversion


    Right now my MVMe boot drive is formatted MBR. I just cloned it over from an older SSD and never changed it to GPT. In any case, I have an old PC I use as a test bed and I've successfully converted boot SSD's from MBR to GPT using Aomei Partition Asst and MBR2GPT without any problem and having the converted drive to boot. In another PC I have that has the NVMe boot drive formatted GPT and booting UEFI, the partitions are EFI, MSR, Primary C and Recovery.If I use either MBR2GPT or Partition Asst, the EFI partition comes after the C partition and there is no MSR partition. My question is this: D

    MBR to GPT conversion

    clone MBR HD to bootable GPT partition?

    Hi,

    1. You cannot convert mbr to gpt without data loss. otherwise, you can follow directions here:

    FROM WINDOWS RECOVERY CONSOLE:

    To change a master boot record disk into a GUID partition table disk using a command line


    • Back up or move the data on the basic master boot record (MBR) disk you want to convert into a GUID partition table (GPT) disk.

    • Open an elevated command prompt (right-click Command Prompt, and then click Run as Administrator) and type diskpart. If the disk does not contain any partitions or volumes, skip to step 6.

    • At the DISKPART prompt, type list disk. Make note of the disk number you want to convert.

    • At the DISKPART prompt, type select disk <disknumber>.

    • At the DISKPART prompt, type clean.

    2. I'd suggest converting your vista drive to a virtual machine, load that up on your windows 10 system and use a program like virtualbox to run it.
