  2. 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.
