Installation from usb completes successfully and tells me to restart (I have an iMac 2010 model that I replaced the hard drive inside b/c it was a failing hard drive---new hard drive seems to boot and actually allows for a quick Ubuntu installation so all is good there).
Once restarted it makes the normal start up sound like a Mac would and then goes a black screen with a white cursor in the middle of the screen (not blinking)...I have tried pressing CTRL-ALT-Scroll and Pause Break...also tried to recreating installation usb via Ubuntu 20.04 Desktop iso with etcher---still getting the same thing with this iMac.
What else can I try to get passed this cursor black screen???
Reset to default
