How to boot from SATA3 drive, but install rest on NVME + PCIE Adapter

  • 772

I have a older PC with mostly SATA3 connections, and wondering how best to keep it chugging along with linux for a few more years.

4 x SATA3 ports
1 x PCI-E card for NVME (not bootable)

Motherboard is a z68 https://www.asus.com/Motherboards/P8Z68V_PROGEN3/

cpu is 2600K intel

I am aware the board likely cannot boot off the PCIE drive.. but how to do Setup a fresh install of drives and partitions so that I can perhaps have linux mostly all installed on the NVME drive (which is significantly faster)

If this doesn't work I might just buy 2 Sata based SSDS, run them in raid 0.. and give up.. but it would be great if there is a way on a fresh install of the OS to setup this way.

Target OS: Ubuntu 20.04 LTS
1 x SATA 3 : Set to Boot
1 X PCIE NVME : /root , /home
system-installation partitioning lvm boot-partition

    This is what finally worked:

    Install Ubuntu 20.04 as usual until you get the the screen that asks if you want to erase Ubuntu, etc etc... you should select Something else, which brings up the custom partitioning dialog of the installer.

    Partitions

    sata drive

    • 1GB for a /boot area
    • the rest formatted as a "System Partition"

    nvme drive

    • 50GB for a root / area
    • the rest is /home/

    thanks to @oldfred!
