Any ideas? Windows 10 came preinstalled and I may dual boot for a while to Windows but I want LM as my main OS. I don't think removing W10 altogether will make a difference. Something to do with Dell's nvme front panel M.2 hardware apparently.

DELL Precision 5820 tower and NVMe M.2 front-panel SSD issues
Hi all,
This post is to summarize my findings on the issues I've had with my new DELL Precision 5820 tower.
This machine came with a NVMe M.2 1TB Samsung SSD and a single 2TB harddrive for backups. It was delivered with Ubuntu 16.04, but like a true besserwisser, that was seen as "old" so we jumped in and set/reset everything in the BIOS to what we assumed it should be ( SATA ACPI, no fancy schmancy stuff, everything enabled about the CPU and so forth). And then we installed KUbuntu 17.10.
And boy did that blow up in our faces.
After a long process with DELL Pro support on the line, I managed to (in my own messy way) bork an installation I had already made to the hard drive (that worked unlike the SSD where we were able to install to it but never boot from it). So I kind of went into random monkey mode (if I push ALL the buttons, I must be able to push the right sequence at some time). And I did. Turning on Intel RAID and Intel SSD Volume Management ( two separate screens in the BIOS) as well as completely disabling legacy boot, have secure boot off (needed for the CPU microcode updates), I was able to install KUbuntu on the SSD _AND_ boot from it.
tl;dr - Even if you have only ONE SSD, you MUST turn on RAID and Volume Management in EFI mode.
DELL have documented this in their knowledge base, but it's worth documenting this here as well since nobody should have to waste their time like I did.
And yes - it IS counter-intuitive to turn on RAID when you don't RAID...
