So I’m trying to setup peppermint os , I have two disks and I want them both to have full disk encryption. After a couple of reinstalls using different approaches, searches and llm questions , still can’t get it to work.

First boot gets to encryption of SDA (I believe) , then to grub menu and I’m able to load the first one. Managed to get new entries but then I get: server error you need to load the kernel first.

I believe both installs are fine and that it is a LUKS thing. UEFI, disabled secure boot.

Sda1 EFI Sda2 root

Sdb1 EFI Sdb2 root

Maybe EFI should only be on one of them?
