A7N8X-E will not boot into windows xp

[LeoMael]

I have tried everything I can possibly try. I just got this board. I installed winxp and everything went fine. Yet if I reboot the computer, I get DISK BOOT ERROR. INSERT SYSTEM DISK AND PRESS ENTER.
I have turned off all options I don't use(SATA, Firewire, onboard sound, Gigabit LAN). If I reinstall windows it'll load as if it see my boot disk, reset it same error as above. I tried my 80gb drive in another computer to see if it was dying, boots windows fine. What gives?

Specs:
Athlon XP Barton 2500+ (stock speeds)
A7N8X-E Deluxe
512MB Kingston PC3200
Radeon 9500pro (stock speeds)
Audigy2 ZS
1x 80GB WD hard drive (boot drive)
1x 40GB WD hard drive (slave)

check which drive bios is tying to boot off of, also make sure to remove any flopies from the drive. Sounds like it is trying to either boot off of a flopy or off of your other drive. If settings apear correct in bios try unplugging the slave drive and see what happens.
