I need a full disk encryption software that is cross platform with Windows and Linux operating system. The issue is the target computer has both OSes installed and has GRUB giving the user the choice which one to boot.
I need a solution that does full disk encryption at sector level + pre-boot authentication. Please do not offer any container based solutions.
I've searched the net for hours and found many solutions but almost all are designed specifically for MS Windows OS. A few are designed for Linux but none is compatible with both.
Anyone knows a good one?
