@Sebastian-Roth So far I’ve tried a fresh Ubuntu 16.04 install, and I’ve even used LVM and just captured as non-resizable with 0 issues. Now while this wasn’t Ubuntu 18, I did notice the machine I had the issue on originally is unable to install this OS due to something being wrong with the “file system” on the disk which for some odd reason it couldn’t format, delete, or write to. It is an SSD, and I couldn’t recreate this issue on any other box. I ran various SSD diagnostics with no errors being found so I’m stumped. I haven’t gotten to try with the exact iso posted above just yet - doing production stuff lately since I’m alone in IT currently.
