I suppose I would try resetting the Bios to its defaults. Make note of any changes you have made so you can repeat those after the reset.
You might think about getting another boot DVD, like Ubuntu or one of the bootable third party partition managers.
It appears from your listing that UEFI boot option is disabled. If that is the case, you should not be seeing any UEFI boot options and should only see the actual drive listed as a boot option.
But something should show up when you have a Bootable DVD in the drive. Using the Boot Device Menu should give you that option.
