Missing OS

[GodPandaman]

I am using an Dell Inspiron 1501 Laptop running BIOS version 2.6.3 and I accidentally reset the bios to the setup defaults. Now whenever I boot up the computer, It states that I have a missing operating system. How do I configure it to load my OS?

This could indicate that the system is booting from the wrong hard drive. You can change the boot order in the BIOS setup screen.
