I have a problem with my Virtual box. When I try to start a guest OS, it doesn't start and I get a black screen. I tried to disable Hardware Virtualization an 3D acelaration but the only thing that changes was the black screen that started to have a white underscore blinking. I also tried to downgrade virtualBox, but it didn't work. I've tried Linux and Windows guest, but nothing changes. If it helps I'm using Ubuntu 20.04 on my host machine.

Any help would be apreciated
