I'm attempting to install Ubuntu 19.04 on a 2019 Dell Inspiron 7490 (service manual). When I get to the point of selecting a partition to install on, the installer can't find any hard drive and I just see an empty list like this:
.
I found this information from Dell about the issue: https://www.dell.com/support/article/us/en/19/sln299303/loading-ubuntu-on-systems-using-pcie-m2-drives?lang=en
Although its a bit outdated. They suggest to first set the SATA operation to AHCI in BIOS. In my BIOS I don't get an option for AHCI as seen below:
Only disabled or RAID. To my understanding, AHCI is a type of RAID so maybe this is the correct setting. Thoughts?
Next, the Dell page suggests changing the Ubuntu boot options to include nvme_load=YES. I have not been able to do this as when I boot the installer from my USB I never see the keyboard prompt so I am unable to enter the menu where they change the boot options.
Does anyone have any ideas or suggestions regarding this? I don't need to keep the Windows installation so solutions that involve removing Windows are also welcome.
