XP does not boot, need Windows XP startup disk

I have a Dell Inspiron B130 laptop, purchased in December 2005, which was running Windows XP Home. When I try to boot, the Dell logo boot screen is displayed, then a Black startup screen is briefly displayed and one line of text flashes by so fast that it is impossible to read it, then it loops back to the Dell boot logo screen again. This process loops repeatedly. After reading the forum help messages, I concluded that I have the exact problem described in the section "Black startup screen is briefly displayed and your computer restarts repeatedly when you try to start Windows XP" http://support.microsoft.com/?kbid=314466 For the RESOLUTION, I need the "Windows XP startup disk", however this laptop did not come with one, only a paper with the message "To learn more about obtaining a copy of your operating system CD or drivers for your computer, visit support.dell.com/pcrt" I have spent over an hour trying to find where I can obtain this CD, with no luck. I want to follow the documented RESOLUTION from the microsoft article, and do not want to loose everything that is on the drive by running the Dell PC restore.
