ASUS Laptop AMI Megatrends aptbios Boot Options

I am working on an ASUS Laptop circa 2012 with an AMI Megatrends aptbios.
I can't get it to boot from anything than the hard drive and the hard drive is the problem.
So, I need to boot from DVD or USB flash.  Neither seems to work.  The DVD doesn't work no matter which DVD / CD I try.

If I start the computer with the ESC key pressed, then generally I can get a menu.
One of the options is to boot from the HD and sometimes the USB if there's a USB stick inserted.  But I've never seen the DVD drive here.
The other option is Setup (i.e. bios)
I'm not sure what is the relationship between the list I see here for booting and what I see in the bios.

I see in the bios settings there's a BOOT section.
In there are "boot options" that are numbered.
The one option that's there shows a very long name for what appears to be the hard drive.  It includes the word "Windows".
There are capabilities there to add boot options 2, 3, etc.
But, I have NO IDEA what the notation is supposed to be to specify anything like that long line mentioned above.
It also asks for the path but I have no idea what drive letters may be assigned nor what "path" notation is expected.

The system is stuck in "reverting" a bunch of updates and we are going to let it run all night.
But, in the mean time, I need to know how to get this sytem to boot from other media.

This is a Windows 8 system from the factory.  I see things about UEFI but I *don't* see anything like that in the bios settings.

I'm hoping for some actual ASUS / AMI experience / examples here an not just guesses.  I've guessed enough already.

look for Secure Boot.

since you said about the bios " But I've never seen the DVD drive here."  i suppose you can have a bad DVD drive
test with another one - if possible

as for your harddrive, you can run diagnostics on it when attached to another , working PC
i use ubcd for this :
Hardware diagnostic CD    UBCD

go to the download page, scroll down to the mirror section, and  click on a mirror to start the download
Download the UBCD and make the cd   <<==on a WORKING PC, and boot the problem PC from it
Here 2 links, one to the general site, and a direct link to the download

since the downloaded file is an ISO file, eg ubcd527.iso - so you need to use an ISO burning tool
if you don't have that software, install cdburnerXP : http://cdburnerxp.se/

If you want also the Ram tested - run memtest86+ at least 1 full pass,  - you should have NO errors!
 
For disk Diagnostics run the disk diag for your disk brand (eg seagate diag for seagate drive)  from the HDD section -  long or advanced diag !  (runs at least for30 minutes)

**  you can make a bootable cd - or bootable usb stick

for completeness -here's how i handle disk problems : http://www.experts-exchange.com/Storage/Hard_Drives/A_3000-The-bad-hard-disk-problem.html

As hinted earlier, look for "secureboot", and turn that off. Systems that were sold with Windows 8.x pre-installed, have an UEFI BIOS, and m$ requires the manufacturers to have that turned on by default. With secureboot on you can only boot from certified media and OS's, this theoretically reduces the the risk of getting viruses that change boot files.

Suggestion to turn the secure boot off is correct. The long name you see in BIOS for the HDD is a UEFI boot idetificator which consists of GUiD names of HDD, boot partition and loader.
It was often so that with secure boot enabled you got no DVD device in boot list if it was not UEFI compatible.
