Well, I established that i simply wasn't doing it fast enough. The 
virtual machine is booting via bios. I think my problem was partly due 
to it taking the screen reader some time to say the virtual machine had 
started, then taking the screen cap plus running it through the OCR 
program (even though i had scripted this) was taking so much time I was 
simply missing the boot prompt. So what I have to do is just start 
typing, trusting that it's there.

PS: Sorry for top-posting. With the screen reader, it's very difficult 
to do otherwise.
