Need help with new install

[kclark]

I just built my first computer and need help with install I think? I have 2-74 gig raptors running raid 0 and 2- seagates im using for storage. I have loaded windows xp up and everything runs fine but when i take out the windows cd and reboot i get an error>>> no boot disk press f1 to retry. The only way my system works is if I put the windows cd back in and rebot? My Bios I have set up to look for removable first then, Hard drive then cd rom? Do I need to reload windows again?

Thanks for any suggestions
