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 did not validate than Ubuntu 20.04 would install correctly but suspect that it would have given the same symptoms were presented.

I am trying to install Ubuntu 20.04.1 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). I found an additional and more up-to-date guide here: https://help.ubuntu.com/community/Installation and as a result was able to also disable Fast Startup, but this did not resolve the issue. Secure Boot was enabled during this install attempt. I am able to proceed through the minimal install with no package upgrades or 3rd party downloads normally until I reach the "Installation type" screen. It never displays any information within the table (i.e. Device, Type, Mount point, Format?, etc.). As a result, I am not able to proceed with the install. As recommended in the first guide described above, 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.
