A HP Compaq 6000 Pro Small Form Factor PC produces the following error when booting up:
Non-system disk or disk error.
replace and strike any key when ready.
There is no CD-ROM/DVD or USB device inserted.
If I place a bootable DVD in the PC, and reboot, I get prompted to press any key to boot from DVD. I ignore that, and the PC will then boot into Windows off the hard drive.
The C drive partition is active, and primary.
This same behaviour occurred with a 2nd & 3rd HDD.
The 2nd HDD test is below, the 3rd HDD tested with Crystal Disk Info without an issue.
I reinstalled Windows on the 3rd HDD with both SATA emulation set to AHCI, and IDE, and the issue remained in both cases.
What do I need to do to boot from the HDD without a DVD inserted?

According to the picture
your HDD will fails soon because you have some uncorrectable and some pending sectors. The BIOS seams to detect this during boot:
and skips the HDD, but still allows you to boot if you ignored a different boot drive like a DVD. Backup all data to a different drive and replace the HDD with a new one.
If you still see the issue after replacing the HDD, load the default BIOS settings, maybe the BIOS stores the error information and this error log must be cleared.
