HP EliteDesk 800 35W G2 Desktop Mini PC (ENERGY STAR)
Linux

I have this desktop mini and I was earlier able to select Boot from removable media in UEFI and was able to install Linux successfully. But now that I'm going over my install procedures (I document everything) I find that when I enter the UEFI System Setup there is no option in the Advanced -> Boot Options to boot from removable media. As such I cannot boot from my Linux installation CD (actually a DVD). My CD drive is connected using USB if that matters. It didn't matter a few months ago when I installed Linux. I have reset things to factory defaults but still no boot from removable ,media option. So how do I get this system to boot from a CD? Any clues or ideas are welcome and appreciated.

I was wondering, in the past when a BIOS was not working well, there was a way to 'flash' an updated BIOS on the system to address issues. Is there a way to 'flash' the UEFI with a refresh  on the system to address this issue? Just wondering.

On further thought, there is a Linux tool named efibootmgr. It purports to manage UEFI boot list entries. I have checked my UEFI boot list but there is no entry for a CD. Does anyone have experience with this and is it a way to tailor the boot menu to be able to boot from a CD? I've read up on it hunting with google, but I don't have a firm grasp on what to set things to, so I'm a bit hesitant. A little guidance would be helpful. Thanks to anyone who can help.

Alright. After doing more research and mounting my Linux install DVD and inspecting the contents, I finally arrived with the command:

    sudo efibootmgr --create --disk /dev/sda --part 1 --label "CD/DVD Boot" --loader '\EFI\BOOT\BOOTX64.EFI'

 

  Ok. The above applied and I see it in the UEFI Boot List when I restart holding down F9 to be able to chose from the Boot List.  But selecting it does not result in booting the DVD.

 

  Doing more research, I came across the comment that maybe an update to BIOS/UEFI can address this. So in the UEFI I selected the update BIOS/UEFI option. It connected to the network and after a while announced that an update was applied. Great.

 

  But trying to boot the DVD with the UEFI Boot List entry still did not work.

 

    I notice that there are no other comments on this, So I'm asking anybody who might have some guidance on this to please chime in. Thanks

Never  mind. There is no reason now to boot from a CD/DVD. So if thing curl up and die I will just get a new system. So ignore all this.
