Hello All. The root cause was determined to be that Ubuntu could not see the installed hard drive, which was verified using a number of commands including 'fdisk -l' from the installation environment. I had another look at the system BIOS settings and changed 'Onboard SATA Mode' from 'Intel RST Premium' to 'AHCI'. This allowed the Ubuntu 20.04 and 16.04 install to recognize the hard drive partitions during the install and still allows Windows to boot normally. I was able to complete the Ubuntu 16.04 install without difficulty after making this change. I suspect that the 18.04 would have installed correctly as well but did not validate this.

I am trying to install Ubuntu 18.04.5 LTS from newly written USB alongside pre-installed Windows 10 on a new Acer Aspire TC-895-EB11 desktop. I expected that the install process would recognize the free partition created on the GPT disk, but it did not. I had previously reviewed and followed the steps in this guide (https://askubuntu.com/questions/221835/how-do-i-install-ubuntu- alongside-a-pre-installed-windows-with-uefi). Secure Boot was disabled in the BIOS on the first failed attempt. I tried again with Secure Boot enabled - no change. The drive & partitions do not appear to be recognized by Ubuntu. As recommended in the guide, I am submitting this bug report. Any assistance would be much appreciated! I only purchased this desktop to run Ubuntu, but would prefer to keep the Windows 10 partition usable in case I ever want to use it.
