This is my disk layout:
500 GB Linux - BTRFS
100 GB Windows - NTFS
400 GB Storage - NTFS (shared between linux and windows)
I want to encrypt everything. For Linux I can use luks2 but what I’m supposed to do for Windows ? (No bitlocker please)
Will veracrypt replace refind boot manager?
Note: I am talking about the one that asks password before boot (full encryption)
If the reason for you wanting to avoid bitlocker is incompatibility with linux, you might want to reconsider. It’s been many years since I had drives with bitlocker+ntfs, but they worked reasonably well back then with dislocker, so perhaps check that out before considering alternatives.
