VT-x is not available (VERR_VMX_NO_VMX) Error

[TimB]

Hello,

I have been using an Ubuntu image for the past couple weeks on a Windows 10 OS with no issues. However last night I was messing with display settings (trying to get an usb-c to hdmi display working). Today I can not get my Ubuntu image to start. Virtual Box keeps throwing this error:

VT-x is not available (VERR_VMX_NO_VMX)

After researching this it seems Virtual Technology was deleted in the BIOS, however that's not the case for me. I even disabled it and got a slightly different error message when trying to run the image in that scenario.

I also have deleted the vbox config file, uninstalled/re-installed virtual box software and nothing has worked.

Here is a snippet from the log file:

*EDIT* Not sure why I didn't think of trying this but I created a new VM and can boot it up. So it's definitely something specific with my original Ubuntu VM. Is there some type of recovery/fix mode for a VM? I had a snapshot from prior and reverted but that didn't help me any.

Can anyone point me in a good direction to fix this? Any help would be appreciated.

Thanks,
Tim
