Howdy kind folk...

I'm getting the following when I attempt to start my (very first) virtual machine:

"VT-x/AMD-V hardware acceleration has been enabled, but is not operational. Your 64-bit guest will fail to detect a 64-bit CPU and will not be able to boot.

Please ensure that you have enabled VT-x/AMD-V properly in the BIOS of your host computer."

That was a moment ago. Now, however, I just got this, instead:

"FATAL: No bootable medium found! System halted."

May I ask what I should do, please?

Thank you!

Sincerely,

The first is a warning, which you should heed if you want to run a 64bit guest. The second is an error.

In order to run a 64bit guest your CPU must support VT-x (or AMD-v), and it must be enabled in your host PC BIOS, and nothing else can be already using it.

The second (error) message means exactly what it says: none of the disks currently attached to the VM contain an OS. Normally, right after creating the VM according to a template, you would mount a Virtual CD/DVD (i.e. an ISO file) in the VM, boot the VM and install the OS. I suspect you haven't done this. Note that VirtualBox just creates the simulated PC hardware suitable for a number of OS's, but no OS setup disks are bundled - you must seek those out yourself.
