Hi!

I would like to use 2 windows based OS, on the same system, while both is seperately encrypted, while sifting between them does not require going into the UEFI/BIOS.

I would like to have a Main OS, and a Sub OS.
The SUB would be a "set to be offline, one app is needed, no internet access" os.
The Main would be, a normally used one.
The main goal to have the SUB encrypted, is just to create a seal on the "open disk area" of it, so it is sealed : nothing can read from it, or write to it. Nothing special.

With bitlocker i was able to do this setup years ago. That was good, because if an OS change ("boot the other!") was needed, it took only 2 specific passwords, selection, and reboot worth of action. The second user of the system would not be confident in the the bios UEFI
Now as i checked the forum here, my key issue is: if even on one disk, i would be able to manage to have veracrypt with 2 OSs, the "OS selection" would happend after veracrypt unlocking (so the main's password is needed to be shared, or the sub's to be used (?).

This is still not clear to me. Is it possible?
I will happily take any advice /guide. I will try it either way, to just get the experience.
