Hello, I am attempting to install Catalina on my Lenovo thinkcentre m93p tiny. I think that the installation was mostly successful, but I have not been able to reach the setup screen. What I get is a white screen with a black cursor. If I click anywhere, the cursor disappears. Tapping the keyboard causes the screen to blink.

Is this something to do with my graphics? I have Intel HD Graphics 4600. I am not sure what is happening. I will attach my EFI folder. Any help would be greatly appreciated. Thanks!

Facing the same problem here.
 
Have you had any luck with this? I’m getting the same gray screen on my initial boot once Catalina is installed.
