Oh man, Ubuntu 9.10 is the fastest OS to boot now! Code named Karmic Koala is not yet released but in Alpha stage. It will soon get released in 2010 but, lots of improvements has gone in to the way it boots. Already, I’m on Ubuntu 9.04 – Jaunty Jackalope and it is lightning fast. I have not really clocked but it is than 40 seconds. Ubuntu is really a good Distro for anyone who is switching from Windows :)
