After showing you guys how to change your XP boot logo a lot of people asked me why bother since I only see it for a second. If you're one of those people then you may want to disable this logo from ever showing up. Doing this can shave a small amount of time off your boot time. The down side to this is you will no longer see any boot error messages. This also bypasses things like chkdsk. ONLY run this if your system runs without any problems.

Find and open your boot.ini file

Your boot.ini should look something like this:

[boot loader]
timeout=5
default=signature(85b37567)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
signature(85b37567)disk(0)rdisk(0)partition(1)\WINDOWS="OS for testing new boot screen" /fastdetect signature(85b37567)disk(0)rdisk(0)partition(1)\WINDOWS="(default)Microsoft Windows XP Professional" /fastdetect

This line is what I want you to pay attention to:
signature(85b37567)disk(0)rdisk(0)partition(1)\WINDOWS="OS for testing new boot screen" /fastdetect
Change it to something like this:
signature(85b37567)disk(0)rdisk(0)partition(1)\WINDOWS="OS for testing new boot screen" /fastdetect /noguiboot

Upon restarting, the splash screen will be gone. It can be re-enabled by removing the new switch.
