I have recently purchased a Dell Window 10 Pro Laptop. Intel i7-10510u cpu, 1.80GHZ, 8GB memory, 512GB SSD /9GB SSD, Touch.


Storyline:

I have been trying to install Catalina OS with Oracle Virtualbox. I actually was successful and logged into Catalina and downloaded Excel to the MacOS system. Everything was working fine until I let the Catalina OS install updates. I then could not get the VM running again. I did a complete reinstall and was able to run the Catalina OS again. However, I had to reboot my laptop and every since I have received the following message when I try to start the VM.


I have been researching a while and started looking at Windows preferences and I tried again with Hyper-V on and off with no success. The option Virtual Platform Machine is on. I get the same error for another version of the MacOS Catalina with same results. Something changed that i can't determine to get this working again.
