Installing Ubuntu 18.04 on Dell XPS 13 9370
I bought a Dell XPS 13 9370 a while back with the intentions of running it as a full time Ubuntu laptop. It’s a very well built laptop with plenty of performance. Unfortunately it has been nothing but pain ever since I got it. First, I was having issues with it booting, which turned out to be a failed CPU - so off it went to Dell. After I got it back, it sat in a drawer for a couple of months before I took some time to actually work on it again.
A couple of days ago, I tried to get Ubuntu Desktop 18.04 re-installed on it and found that the installer did not see the NVMe drive. So I opened her up and swapped out the drive for a known working one. Same problem. This time, I was feeling pressed for time and annoyed so I took it to a local Dell service depot. They were able to install Winblowz, so I know that the drive works. Okay, back to the settings.
I determined that the SATA Operation setting in the Bios (F2, BTW) was set to RAID, which does not work in Ubuntu or several other Linux variants. So I swapped it over to AHCI and everything worked as planned. Now, I just need to get my hands on another 2TB NVMe drive, so I can sync my entire desktop Home directory to my laptop.
I hope this helps!
