I have an Inspiron One 2320 with an interesting issue.

Upon cold boot I get the message "Reboot and Select Proper Boot Device or Insert Boot Media."

If I hit F12 on reboot I can select "Hard Disk" from the options and the computer boots up fine.  If I reboot from this it boots up fine.  

But if I turn it off and then restart I get the message about selecting the proper boot device.

In the Bios:

-Hard Drive is selected as first boot device

-Bios system time is correct

-Bios recognizes the hard drive

The machine has some years on it so I wonder if it's just something where the Bios isn't holding the setting even though displaying the proper time contradicts that finding.

Thanks for your time.
