Hibernation[0] is when the computer shuts down after writing the OS 
state to disk. Suspend[1] (sleep, stand-by etc.) is the low-power 'I 
just closed the laptop's lid' mode. You can hibernate Windows and boot 
up into Ubuntu and vice-versa. You can't boot up another OS if you're in 
suspension.

Again I don't know how, but Windows doesn't like it (and maybe Ubuntu 
too, I've never tried it) if you write to it's partition while it's in 
hibernation.
