The computer arrived today in the mail. I unboxed it, and ran through windows 10 installation setup. Then I set it to sleep mode while I finished my work day.

 Create a thumb drive containing Ubuntu 20.04 LTE
 Install Ubuntu on "desktop"
 Guide from Dell for installing Ubuntu
 Thorough guide for installing Ubuntu (if you run into problems with steps from ,  or )
 Guide to install windows 10 again if ubuntu install fails.
I have a ubuntu 20.04 LTE boot thumb drive that I had used previously to setup ubuntu on an older laptop. 
My hope was to use this thumb drive again, but for the new laptop ("NL").
I booted NL from the thumb drive, and all went well.
To do this I had the thumb drive inserted while the machine was off, then I turned on the machine by pressing the power button. I held down the F12 button from the very start of the boot, until reaching the BIOS/UEFI screen.
At the BIOS/UEFI screen, I picked [TBD].
I was able to connect to my home router, surf the web, open a terminal in a new virtual workspace, do a sudo apt-get install curl, make a curl call [curl -k -v -x GET https:// TBD ], and open a new file finder in a new virtual workspace there as well. There were no freezes, slow downs, or hiccups. Everything just worked.
Based on the screens I saw during bootup of NL, and the packing slip that came with the laptop, I wonder if Dell set up this laptop to be compatible with ubuntu install.
