Blinking cursor on black screen using Virtualbox [closed]

I'm trying to install an Ubuntu virtual machine on my Windows 10 laptop to do work on it. I've been following step by step tutorials, but when Ubuntu should boots and show me the desktop, I'm stuck with a blinking cursor on a black screen.

I've tried the nomodeset stuff and nothing is working. I've changed the Ubuntu ISO and that didn't work either.

I also tried with Vagrant, with a 32 and 64 bit Ubuntu, but both froze at SSH auth method: private key.

What am I doing wrong?


I've solved it. I had to turn on Intel VT-x in the BIOS options.
