Debian is the only OS there now. If I encrypt /, home, and swap, it won't boot after install. If I leave them unencrypted, it boots fine.

To satisfy my curiosity, I fired up a VM and in the VM used the Debian installer to automatically partition for an encrypted install, with separate /, /home, and /swap. It made a 1MB blank partition, 512MiB /boot/efi partition flagged as bootable, 244MiB /boot partition, and allocated the rest of the disk to the LUKS container. In the LUKS container contained /, /home, and /swap. See the attached picture. After installation was complete, here is the output of lsblk. NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 20G 0 disk ├─sda1 8:1 0 512M 0 part /boot/efi ├─sda2 8:2 0 244M 0 part /boot └─sda3 8:3 0 19.3G 0 part └─sda3_crypt 254:0 0 19.3G 0 crypt ├─debian--vm--vg-root 254:1 0 6.4G 0 lvm / ├─debian--vm--vg-swap_1 254:2 0 2G 0 lvm [SWAP] └─debian--vm--vg-home 254:3 0 10.9G 0 lvm /home sr0 11:0 1 55.3M 0 rom It seems the best practice is: 1MB blank partition at the beginning of the drive 512MB EFI partition (or larger) mounted at /boot/efi, flagged as bootable 256MB /boot partition (or larger as desired), NOT flagged as bootable. Then the rest of the drive partitioned as desired (ie a LUKS container) If all of these conditions are met, then encrypted boot with EFI *should* work correctly. So I'm at a loss, D&P Dimov, as to why you had difficulty. You said it was a config in your BIOS that you needed to change?
