Black screen after creating ubuntu VM

[smaiderman]

Hello everyone. I wonder if you can help me. I'm a total "not windows" noob, and I'm trying to set my Unraid NAS (core i3 13100, 36GB ram, 56TB) Yesterday I did my first install, and ended up messing with something wrong I then re created the usb install, and started fresh. Today, I thought, lets try things in virtual machines, in case I break something. I managed to create a share and access it via windows network (such a score for me ), transferred the iso to the isos share, and tried to create a VM for ubuntu. I read the options, and the only one I could understand was the GPU. I changed virtualized to the i3 iGPU. As soon as I tried to start it, my screen went black (I guess you cant choose the gpu u are using in unraid to be the one used in your VM) I accessed via windows http://servername.local/Dashboard , and went to delete the VM, but there was none.
So I thought, lets reboot the system. And now I'm stuck, the black screen is still there, and I lost http://servername.local/Dashboard access.... I want to create a Plex Media Server, but I don't want to move to a completely new OS and risking to lose all my data (currently 26Tb of media) I wonder if there is a safe way to start in Unraid OS or do you think I should stay in windows...

I didnt think to read the forum, and now I read that it is important to habe the logs BEFORE restarting... but now it is late.

I didnt have any plugin installed, and I am using the last unraid version.

Thank you!

Do you know your disk assignments?

Do you have the file 'config/vfio.cfg' on your flash drive.    If so then try deleting that to see if the system then boots as that file is used to specify hardware that is passed through to a VM and is therefore unavailable for Unraid to use.

 

BTW:  When first trying with the VM start by NOT assigning any graphics card to the VM and let Unraid emulate one that you can access via VNC.  You only need to pass through a GPU if you need to maximise performance of the GPU.

Do you mean what disk is cache, parity and storage? Yes, I do know

That file is not present in the flash drive sadly

[smaiderman]

well. I tried formatting the flash drive and creating it new, but I'm still in the black screen. Should I reset bios settings?

I managed to solve 

 

I entered the bios (MSI) disabled both fast boot options, and fixed the boot order to use the USB as 1st option

 

Thanks to every participant trying to help
