I have an unencrypted Windows10/Manjaro dual boot on a 256Gb SSD, plus a 1Tb HDD, where I store most of my data.
The partitions are organized as following:
1Tb HDD :
|_ sda1 : exFAT partition, readable by both W$ and Linux
256 Gb SSD :
|_ sdb1 : EFI system boot partition
|_ sdb2 : Microsoft reserved partition
|_ sdb3 : NTFS Windows system partition
|_ sdb4 : NTFS Windows recovery partition
|_ sdb5 : ext4 / partition for Linux
|_ sdb6 : ext4 /home partition for Linux
|_ sdb7 : linux swap
The bootloader is GRUB, and allows me to choose between the two systems.
What I am looking for is a way to encrypt both hard drives, and decrypting them by entering a password before GRUB. Of course I would like to keep the existing partitions, the fact that both systems can read the contents of the 1Tb HDD, and not break GRUB (if possible)
Do you guys have any ideas ? I have already checked Veracrypt for windows and LUKS for Linux, but Veracrypt seems to break GRUB and encrypts Windows only, and LUKS is Linux only.
