[solved] LVM on Luks installed on second HDD in laptop won't mount

I've added a second HDD to new (to me) Lenovo W541. The first drive is setup BIOS/MBR and I've set up the new drive the same, MBR basic configuration and chose Grub for the boot loader. I've followed all of the instructions here in the wiki.

+ -- sda  (windows)
+ -- sdb  (arch)
|-- sdb1  /boot
|--+ sdb2   
   |--+ Luks
      |- swap    /LVM-swap
      |- root    /LVM-root
      |- var     /LVM-var
      |- home    /LVM-home

I didn't have any trouble, and I can only guess I performed something out of step (it got a bit hinky between `mkinitcpio.conf`,  config Intel microcode updates, and choose a boot loader--grub).

I can unencrypt the Luks partition, mount the new system's files, and `arch-chroot` into the new install.

I read I can start the system from BIOS setting by choosing the second HDD in the BIOS.
But after I select drive it boot goes right back to BIOS.

What might be going on?

I've followed all of the instructions here in the wiki.

If this is true, that's surely the problem. You aren't meant to follow all the instructions in the wiki, but only the ones relevant to your hardware and needs.

If you know you did it all right, there isn't any point in asking - clearly, you just have gremlins and there's not much to be done about them. Otherwise, how can we know where the mistake is if you don't tell us what you actually did?

It sounds as if you didn't install grub correctly, but that's just a guess.

Was your boot partition mounted correctly when you installed grub? What is the contents of that partition? What is the output of fdisk -l? What is your mkinitcpio config? What command did you use to install grub?

I installed Grub against the boot partition (sdXY) instead of the drive (sdX).

I've learned my lesson from my last two installs of Arch, and I copied the commands as I navigated all of my notes and the wiki's suggestions. I was able to reapply the commands and the laptop is running just fine.
