    Dual Win 10 Boot wanting to upgrade one OS.


    I have a dual boot running two of the same version of Windows 10. One is for work the other is for gaming.

    I would like to upgrade my gaming one to Windows 11 but keep my work on Windows 10. They are both currently activated as one PC if that makes sense. The work Windows was the first to be installed and Im pretty sure the boot loader is associated with that partition.

    Can I perform this upgrade while keeping the work Windows 10 as is and is it recommended? Can anyone give me advice?

    Welcom to the Forums

    Please edit your profile with ALL your hardware specs. It will help us to help you
    System Specs - Fill in at Ten Forums

    Are the two Win 10 versions on same drive or on different drives?
    Does the computer has the hardware requirements?

    Make a drive image backup before you begin.

    Please post a whole window Disk Manager image of ALL your drives. Don't forget to expand the columns so we can read them. How to Post a Screenshot of Disk Management
    If you have a MiniTool or AOMEI Partition use it instead or Windows disk manager.

    The boot loader is associated to both operating systems with no preference. It is located on a partition outside of both operating systems as file systems are not the same.

    Disk management displayed:

    a) Five basic data partitions

    b) One primary partition

    c) Disk 1 RAW reserved partition


    Usually a primary partition is MBR.


    1) Please boot each G and C and run:

    Yes. Just upgrade the one you want. Both will coexist as dual boot and both wil remain activated.

    Ignore all that nonsense about posting extra info.

    Upgrades can fail and then you've wasted your time trying to upgrade.

    Also there can be problems related to failed upgrades.

    If you've made backup images then you can get away without checking.

    If you've not made backup images then it's best to run the scripts in the earlier post and ignore the comment made in post #6.

    The drive with the two OS is UEFI-GPT. You can upgrade one or both to Win 11.
    - As already mentioned, make a drive image backup before you begin.
    - Detach (SATA or power cable) of the other drives
    - I suggest you boot from the Games Win 10, and do an in place upgrade (download the win 11 iso using MCT , mount the iso and run setup.exe)

    If you want to keep the work OS on Win 10 you should block auto upgrade to win 11.

    The first problem you have is that you don't have enough free space on Gaming to do the upgrade to Windows 11. I would boot into each Windows separately and in a command prompt with admin privileges run the command:
    Code:
    reagentc /disable
    Run the command in both Studio and Gaming Windows. Then using a partition management program such as MiniTool Partition Wizard Free, delete the recovery partition between Studio and Gaming, and then move 64 GB from Studio to Gaming. You do not need to leave any free space between them. Then just do the simple upgrade that @cereberus suggested in post #6. You do not need to unhook any other drives for an upgrade. You don't need to run any scripts. You don't need to worry about MBR. @cereberus has it right.
