Hi, Sara.

If you press the 'Esc' key, you will see the boot messages, which might
help you to work out what is going wrong. Are you running the 'OVA' VM
that Tim created or did you install Bio-Linux from an 'ISO' image?

What is your host OS?

One problem might be running Unity, which requires hardware graphics
acceleration. Without it, Bio-Linux/Ubuntu 14.04 will default to a low
resolution screen and performance will be terrible :-(

Please give us some more details about the host OS and which Bio-Linux
VM you're using. It would also be useful to know if you've upgraded your
Bio-Linux 8?

Bye,
