From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

two PMOS installs with LUKS (hexbear.net)

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?

You want to install the same OS twice? But booting the first one doesn't work?

Two EFIs are fine, if you want to switch using your motherboard's boot selection. If you want to switch between the two using Grub one unencrypted boot partition after the first EFI is probably easier. But if your motherboard's boot loader is easy to reach using that to switch is probably the easiest way.

But apparently you cannot even boot into one OS. i would abandon all thoughts of two OSs and concentrate on getting one to boot. Did it work before you installed the second one?
