Hi, after 2 weeks of trying, I got Catalina working on HP 800 G3 SFF, I7 7700, Intel HD630, 16GB RAM, Samsung 256GB SSD drive. I had to swap the Sata SSD drive with a SATA drive to get it going. How do I get it working with the built in SSD drive ? I am getting "An error occured while preparing the installation. Try running this application again."
For some reason, I cannot attach .gif or .jpg
