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
