Hey, I am trying to install a Ubuntu VM. After the installation I need to restart Ubuntu, and when it starts up again all I get is a black screen. So I stop the VM and start it again I get to the meny where I can install ubuntu or try it etc. It wont boot in to the OS.

 

I have tried to detach the ISO, but nothing happends when I do it.

 

note that I have ryzen hardware, I don't know if that has anything to do with it but I think it's worth mentioning.

Are you using SeaBIOS or OVMF?  Try SeaBIOS.  Redo the VM, and hit advanced.

Tried again with Seabios, but now I am stuck in a screen with the text "booting from hard drive" 

Having the same issue with Ubuntu Desktop and I can’t even get past the first part of the install. Blank screen or disconnect seem to only happen when I’m using a VNC client, but not with the built in web client. I’m running Intel Xeon. Thinking about giving up Ubuntu and find something else to use. 

I'm having the same issue too... 

 

It will install and they start up but when I update it and restart it messes up..

I have a ubuntu VM that had some of the same problems. I managed to get to the login screen and switched to xorg profile and it starts up Everytime using that. If I try that first option it just sits at a blank screen. This is in VNC.

I moved onto Debian with xfce and so far has been fine. (Intel Xeon)
