I was having the same problem. For me it turned out to be that I had accidentally set one of my shares "Minimum free space:" to 300GB instead of the intended 30GB.

I've been using Unraid for about three years now, ever since I decided that it was unnecessary to have two computers running 24/7. I used to have a small server with a few VMs and my gaming PC. But then I heard of Unraid and thought: why waste the money and energy on keeping two machines up to date, when I could use all that money and save energy while getting a single better than both solution. Now I'm happily gaming on a VM while running everything else a lot simpler and safer than before. I have been a victim of 2 drive fail RAID5 before and at the time I did not realizing the importance of a good backup. Nowadays i feel safer than ever before. And the community around Unraid is just the best! Happy birthday!

I had a similar problem when I was trying to install Windows 10. Windows was installing fine over VNC, but as soon as I changed to my graphics card it booted up, but I only got a black screen. I tried to install the graphics drivers over VNC, and it looked fine, but never really installed properly. So my solution was to setup RDP, then edit my VM and connect my graphics card and reboot. Now it starts up with a black screen same as before. Next step is to login through RDP from a different computer, and from there install the proper graphics drivers and reboot. Hope this helps
