Installing Ubuntu Utopic in VirtualBox
When I was installing Ubuntu Utopic 64-bit (14.10) inside VirtualBox, I was getting a messed up screen when booting from the ISO.
At first, I thought I would have to update VirtualBox to get support for the new version of Ubuntu and I wasn’t ready to do that upgrade yet. After I finally got time to upgrade VirtualBox to 4.3.20, I was still getting this. After some Googling, I found this article which stated that you just need to switch back and forth from a virtual console (CTRL+ALT+F1) and back to the console where the X Server is running (CTRL+ALT+F7). When I do this, my host (Ubuntu Trusty) switches virtual consoles.
I found out that you can use the VirtualBox Host key (defaults to Right Ctrl) + F1/F7 to do this in the virtual machine. After switching back and forth, now I can install Utopic 64-bit (this didn’t happen for me on 32-bit).
