Dual boot with auto-hiding partitions


New Member
My idea is to setup a dual-boot system with Windows 7 and Windows 10, and want each OS don't see each-other (drive C: partition).

Windows 7 is the main OS, Windows 10 is for the old softwares and the old devices that come with the applications, which are only support Windows XP or previous version Windows.

Is there a simple way to do that?

The MS boot manager does not utilize the "hide" bit, though it does acknowledge it.
i.e. It won't boot a hidden OS, but it's incapable of manipulating the bit to dynamically hide/unhide partitions.
You would need a third party boot manager with that capability designed into its architecture.
Or more simply, you can remove W10's disk letter (using Disk Management) when booted into W7, and vice versa.
Partitions without letters are not displayed in Explorer, so are effectively invisible (and inaccessible) to the end user. (except to Disk Management which will show the drive sans letter so that you can re assign one if you want to undo the invisibility)
