I had to replace my HDD, sea gate barracuda 7200.12 I bought a western digital hd and now when I try to boot I still get boot from media and it will not boot from media. The media I'm assuming it's looking for is hp recovery discs or a fresh version of windows. I have a windows 7 ultimate and it is unable to boot from media. CD Rom and HDD are not being detected by bios. Any help would be appreciated!!!
