nvme booting on legacy mobo?
by babag from LinuxQuestions.org on (#5KZNX)
i see a lot online about being able to boot from an nvme ssd on a legacy mobo by things like using a boot manager and/or moving boot elements around. i've not been able to get any of this to work as yet.
my system is a ga-x79-up4 mobo running ubuntu studio w/kde. system drive is a sata 2.5" ssd. i have a samsung ssd 980 nvme mounted on a pcie card as the mobo has no m.2 slots. it currently has a fresh manjaro install on it as a test. when i installed manjaro, i removed the main system drive (ubuntu studio) so as not to do anything bad to it. the manjaro install usb flash drive found the nvme drive and installed to it without issue, as near as i can tell. the ubuntu studio system is also able to see and use the nvme drive. i just can't boot from it.
when i reinsert my ubuntu studio drive and boot into ubuntu studio, i am able to run grub-mkconfig and it does find the nvme drive and insert it into the grub menu. when i reboot, however, while the grub menu does show manjaro, it does not boot, displaying a message that a kernel must be loaded first. i've tried every combination of uefi and legacy boot settings i can think of in the bios.
i can only guess that this is pointing to the full ubuntu system's ability to find and use the nvme drive but the boot system's inability. in other words, when the full system is up, there is enough resource, like drivers, to find and use the nvme but, during the boot process, when there are more meager resources available to the system, the nvme cannot be utilized.
admittedly, i know almost nothing about how all of this works but am seeing enough online about people successfully booting such a system to think that, if i can just find the right path to navigate a setup, i could get this to work on my system as well.
any help is much appreciated.

(btw, i can't just upgrade right now as changing resources like a mobo would cascade into having to upgrade a lot of other components as well.)
