Most pre-2015 computers, like my HP Z230 workstation, are only able to boot off of SATA disks. While SATA SSDs are perfectly adequate for most workloads, I wanted to install my operating system on a much faster PCIe-based NVMe SSD.

Despite being able to boot from SATA disks, you can effectively trick an older computer into loading an Linux off a NVMe SSD by installing the GRUB bootloader and boot partition on a SATA SSD or hard drive.
