Please bear with me- This might not seem like a big deal to most of you, but I'm happy this was able to work. I was finally able to successfully install Linux on my (2015) Dell XPS 13. :-)
I know, it's a laptop that has a 'developer' edition' with Ubuntu installed on it, but I could never make it install properly no matter how many times I tried, that is until just now. Enabling UEFI and disabling Legacy in the BIOS weren't enough to get it to install, but after resetting the BIOS back to factory I was able to get Ubuntu installed. It's a shame that it's an older version (14.04), but for now it will do until I can get the newer release loaded on it.
Got Chrome, Steam, and my media play of choice loaded and everything seems to run well. :-D
