sorry for the confusion,
so I added a secondary hard drive, my primary hard drive is in sata port 2 and is second on my boot order after the cd/dvd drive. The hard drive i added is on sata port 4. This is all i did as far as setting which hard drive to boot from. Did i miss a setting?
when i started up the PC i recieved the b0 error, so i unplugged the hard drive i added. So im where i started with only my primary hard drive connected in sata port 2. Then i restarted, but still got the 'b0' error. i cleared the cmos and still get the 'b0' error.
