    How to restore or convert an mbr system image to gpt format

    Hi,

    Are you talking about TWO instances of Win 10 running, or are you wanting to overwrite the Win 10 GPT partition with the MBR Image ?...

    Loading the MBR image onto the GPT partition might work without any issues, but there may be some... The GPT installation probably uses a EFI partition and "Windows Boot Manager" to boot... the MBR installation does not...

    If it does not, a Startup Repair may resolve the problem...

    I have had mixed success switching between MBR and GPT installations of Win 10...

    Depending on how you created the System Image, it may refuse to load onto a GPT drive... The Windows imaging method is pretty finicky about stuff like that...

  3. Installing windows 7 on a partition running 10 home so i can install 8.1 pro, as windows will then recognise an upgrade..

    I'm trying to install windows 8 pro for dual boot. Problem is, as u know my (10 home) is MBR table on EFI system.. If I run cmd> command >diskpart list disk> It will be disk 0 , as I have a (1tb) Drive. I cant run cmd >clean , then convert
    to GPT. If I clean I will lose my data.. I tried to convert the table from MBR to GPT without cleaning so I could partition the drive during install , to no avail.. I have a license for 8 pro.. I'm thinking I cant Convert to GPT from MBR without the cleanse..
    Thus I would need another HHD to run the GPT conversion. so I can select that drive. Is it possible to convert, the 1 hard GPT so I can partition for dual boot? At first I was thinking, windows 8 will not recognize an upgrade on a deleted partition, so
    I was thinking , If I partition and install ( 7 ) then install the (8 pro) on that partition it will then recognize the upgrade.. Is there a solution ? Thank You , and that's what we do.. Brettman prettymuch !

    Why not just convert drive to gpt - very easy to do?
