    Windows 10 installer don't detect NVMe drive

    Thanks. This helped but only partly.

    NVMe disk is now listed in choose-disk step but installer says that its unable to install WIndows on this disk because it has MBR partition. Windows can only be installed on GPT disks in EFI systems.

    What should i do now ?

    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.
