I have multiple OS on my machine (debian, ubuntu and windows) I already have ubuntu and windows disks encrypted separately.
I'm thinking about backing up all my data and reinstalling everything this week end, I want to know if there's a way to encrypt my entire disk instead of encrypting each OS.
I don't know how to do a hardware-based full disk encryption (from the wiki page this may be the solution to my answer), I know the risks of doing such operation I just don't have enough information to start with. How to know if my HDD supports it ?
It would be very helpful to have any documentation about this process.
My HDD is not compatible with hardware-based full disk encryption. I've found this https://security.stackexchange.com/questions/14227/multi-boot-with-full-hard-drive-encryption-and-pre-boot-authentication but not sure if it's still relevant. Could it be the answer to my issue ?
