Having Problems Booting up Windows XP

[Matt]

I bought a Hewlett-Packard computer about a year
ago, and a virus totally corrupted my windows files and I
was forced to format my hard disk and re-install my
Windows XP OS with my upgrade disk. Now Im getting a
problem with booting up Windows, I get an error message
saying "BOOT DISK FAILURE, PLEASE INSERT SYSTEM DISK AND
HIT ENTER". I realized that my OS will boot up if I have
my Windows XP in my CD tray, however. I do not understand
why this happens, I should be able to boot up my computer
without my upgrade CD in there. Somebody please help me
out. Thanks

Go into the BIOS and change the boot order to boot from the hard drive
first.
