My computer gets stuck on the blue HP bios screen. Whenever I try to press buttons on my keyboard to get into the boot menu/bios options (F keys), they do not respond. I cleared the CMOS and tried it again to no avail. Then I removed the hard drive and voila: I was able to press the F Keys to get into the boot menu/bios settings etc. I put a recovery disc in my cd/dvd drive and chose to boot off the cd drive. A black screen then appeared saying "Reboot and select proper boot device or insert boot media in selected boot device". I pressed some buttons but the same message keeps appearing. Any help?
