XP pro installed but wont boot from hard drive.

i posted a little earlier with a problem getting windows xp pro to fully install on a new machine a friend built for me, but i finally figured that out!... but now i have a new problem:

after the entire thing installed and i restarted it, now it doesnt want to
boot from the hard drive. in the bios it IS set to boot from the hard drive first so i have no clue why it wont do it when there's a fully installed copy of xp pro on it. so i still basically have a nonfunctional computer since all it will do it when i turn it on is go to the motherboard screen that gives me the option of updating the bios (did that already) or going to the POST screen.

also, my boyfriend thinks it may have trouble recognizing IDE devices (the hard drive and cdrom in particular) which might explain why it was reacting so slowly at the very start when all it had was a motherboard screen. it took about 2-3 minutes to react when i hit a key on the keyboard and about 4-5 for it to realize if i had the windows cd in there and begin installing it. i dont know if this has anything to do with its inability to boot from
the hard drive as well. any ideas on how to fix these problems?

here are my computer's main components:

ASUS "A7V400-MX" VIA KM400A Chipset Motherboard for AMD Socket A CPU

AMD Athlon XP 2200+, 266 MHz FSB, 256K Cache Processor

pqi POWER Series 184-Pin 512MB DDR PC-3200

Western Digital Special Edition 80GB 7200RPM IDE Hard Drive, Model WD800JB


thanks!

Did you have the bios antivirus disabled when you installed XP? If not, it can't write to the boot sector.

Is the WD drive jumpered to master with no slave drive present? You can't do that - it must have the jumper removed or set to Cable Select.
