Dual boot encryption secures data by protecting both operating systems.
Dual boot encryption secures data by protecting both operating systems.
You're looking to combine Windows 10 and Manjaro on your laptop while securing the Linux side. If you enable full disk encryption, it will protect the entire drive, including both the Windows and Linux partitions.
Only the primary Linux disk will be secured. Manjaro's startup drive (may require creation if missing) and the Windows setup will stay protected without encryption.
