When I start a virtual machine with Linux, Ubuntu, I get a message that says:
error invalid magic number you need to load the kernel first

and it just lets me press any key and returns to the Linux installation screen.
What's going on?
 
This might indicate data corruption. You could compare the hash value of the downloaded iso against the one from the source to find out.
