Another way??? If I understand you correctly... open the boot.ini file and delete the second of the two entries. It should look like this... The "30" refers to the time you have to wait on Windows to start itself up, unaided.

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOW S
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Micro soft Windows XP Home Edition" /fastdetect /NoExecute=OptIn
