    Prevent HDD auto-mount

    Hi, everyone!

    I've just installed a dual boot system, with two Windows 10 (one for work, one for gaming). I have a single HDD with two NTFS partitions for the two OS.
    Let's call the two OS Win1 and Win2.
    Win1 maps his own partition (system partition) as C:, and Win2 partition (seen as data partition) as D:.
    Same, Win2 maps his own partition (system partition) as C:, and Win1 partition (seen as data partition) as D:.
    I don't want to share things between the two systems. So, I want that Win1 will display just its own C: drive, without auto-mounting Win2 drive as D:. (same behavior dor Win2)

    Is there a way to do so?

    Hi @mix, Welcome to TenForums!

    In Windows you can 'hide' a partition by removing its drive letter. You can use Disk Management to do this, find it in: Control Panel > System and Security > 'Create and format hard disk partitions' (or just type Disk Management in the Cortana/Search box next to Start).

    In Win1, run Disk Management and right-click on its D: partition. Select 'Change Drive Letter and Paths...' then click the Remove button to remove the drive letter D:. Now do the same in Win2 to remove its 'drive D:' (you'll notice that Win1 and Win2 have different letters for the partitions, Win2's 'drive D:' is the partition Win1 sees as C: ). You should now find Win1 and Win2 only see their own C: drives.
