Cannot boot from new hard drive

[Lobsterdore]

I recently purchased a 500gb Seagate barracuda hard drive (http://www.dabs.com/productview.aspx?QuickLinx=3W4M), I can format the drive and use it as normal, but as soon as I try to boot from the drive it fails, I normally get a 'non-system disk' error upon boot up after installing windows xp 64, I know there is nothing wrong with my xp cd as I can install from the cd on other machines without a problem.

I've tried repartitioning and re-formatting using the windows management tools but this doesn't make a difference, the problem still remains, I've also tried using the windows fixmbr utility to no avail. I've also tried using the various file system utilities off the ultimate boot cd (which includes seagates dos utilities) and that hasn't helped.

I have two 250gb sata drives in a raid array already installed, these work fine and I can boot from them without problem, so my motherboard has no problem with sata drives, I usually disconnect these when I'm fiddling around with the new drive, I also make sure to disable raid and set the boot order accordingly.

I really can't figure this problem out, any ideas as to what could be wrong? Like I said, I can access the drive normally without a problem, it's just when I boot from it that things go wrong.

My specs are:

AMD athlon 64 3200+
1gb unbranded memory
Asus A8n-sli motherboard (http://www.asus.com/products.aspx?l1=3&l2=15&l3=148&l4=0&model=382&modelmenu=1)
Radeon X850 XT
Creative audigy 2
Windows XP 64 pro

Make sure the drive's partition is set to Active (FDISK) and make sure you have the BIOS set to use that specific HDD to boot from, the one you just installed XP 64-bit on.

Ok I solved the problem, what I had to do is put the drive into it's own raid array and now it works fine. I'd imagine that I had to do this because my original raid array was set to be bootable, and even though my raid controller was disabled it might have been confusing things somewhat, well thats the only explanation I can think of anywho's. Thanks for all the help
