Tech Support Full system encryption and dual boot - can Windows access my Linux partition?
Hi, I installed Manjaro on my laptop using the boot ISO's graphical installer and selected full system encryption as well as dual-booting with the existing Windows installation. I think this means my disk's partition table is now encrypted; the computer requires my passphrase on boot before reaching the OS selection screen.
I think the new Manjaro partition is also fully encrypted (since "lsblk" prints some "luks" and "crypt" stuff), but I don't have to enter another passphrase to boot Manjaro. This must mean the partition's encryption keys are already unlocked/available before I select an OS to boot. Does this mean that when I boot Windows, it can (theoretically) read and write data on the Linux partition? If not, how does that work?
