To disable the XP splash screen this will speed up the overall boot process slightly. But remember removing the splash screen will also bar you from seeing any boot-up message that might come up (for instance, if there is a system crash, the chkdsk screen will not show up, nor will tools like convert, etc). However, if your system is problem free, it should be not a matter.
To disable the boot logo, right-click on ‘My Computer’, choose ‘Properties’ and then select the ‘Advanced’ tab. Under the ‘Startup and Recovery’ section, click ‘Settings’. The again in the ‘System Startup’ section, click the ‘Edit’ button of the ‘Default operating system’ section. Now the boot.ini file will open in a Notepad. Edit the boot.ini. Add ‘/noguiboot’, right after ‘/fastdetect’. Make the necessary changes and save the boot.ini file. Make sure you create a backup of the file in case you mess it up. Now when you restart, the splash screen will not appear. It can be re-enabled by removing the new switch.
