64-bit versions of Windows 7, Vista, Ubuntu 9.04 and 9.10 fight it out for the fastest boot time on identical hardware.

Windows 7 is drawing raves from pretty much everywhere these days–many of which are the result of direct comparisons to its oft-derided predecessor, Vista. Windows 7 definitely seems to have Vista beat as far features, security, and ease of use go, but what about speed concerns?

We’ve seen some conflicting reports, in terms of system boot time, so these two guys decided to put the two OSes to the test. They loaded Windows 7 Ultimate 64-bit and Vista Ultimate 64-bit on two otherwise identical Lenovo Thinkpad T400s. Which system booted up faster?

The above video captures the second boot for both systems. They rebooted both computers a handful more times, and retried the test later in the day. You can see the decidedly different results below.
