Windows XP Service Pack 1 breaks the custom boot screens!
from
WinCustomize Forums
I installed XP Service Pack for XP Pro one on a workstation with "Rocky Shore" boot screen and the computer refused to boot with the "custom boot screen" active! I had to reboot into safe mode using the CD - the hard drive safe mode only crashed the computer as well! I deleted the boot.ini file and rebooted and got back in. I recreated the boot.ini file WITHOUT the custom boot screen and all is well! Freaking M$ pack ruins the pretty boot!!! Linux is STILL king!!!
