OK. Do you have a USB key you could try instead?

It is _possible_ it is a bad burn or something.

Is that _Optiplex_ 780?

Then the BIOS is F2 and the boot menu is F12:

Suggestion:
Press F2 when the Dell logo appears. Look for the "boot" section of
the menu. In there, look for a choice to change the order of boot
devices.

Move CD/DVD/optical drive to the top. After that, USB/removable devices.

*Then* the hard disk.
