This problem started with one of the kernel updates about 6 months ago and still continues today. It has been somewhat fixed with some of the updates. My HP laptop will now boot without holding a key down as long as it has the power supply plugged in.... without it, it will not boot without repeatedly pressing a key (any key) .
This problem has been written up on the Ubuntu site.
I found the fix for me on another thread on LQ
add "hpet=disable" to the boot options
