I have exactly the same problem. No idea how to fix it!

I reinstalled the image file and then did not resize the main window. Or you can resize it to Scale as given in menu. It works then.

It sounds like your download is somehow corrupted. I've just downloaded it myself and it loads up in VirtualBox just fine.

Please download it and try again. Cheers!

UPDATE - I managed to track it down. This isn't an issue with the VM itself but the laptop or desktop where you're running VirtualBox, particularly on machines where it doesn't have a lot of CPU-processing power.

When you import the VM image, 3D acceleration is enabled by default:

Machines sometimes can't handle this correctly and end up displaying a blank screen. The workaround is to disable 3D acceleration in the settings (uncheck it in the "Display" tab):

This should stop VirtualBox from loading a black screen when you start the VM. Cheers!

The image is fine, I re-installed the image and it does show the screen but when I close and restart VM it again shows blank screen. It shows desktop of Ubuntu for the very first time

@kadnan_172698 @rafal.sroka.it_190557, I figured out the problem with VirtualBox. I've updated my answer with a workaround. Cheers!
