You can Reset the BIOS to Default Values and see if that will make a difference.

Thanks for your response LSUFAN51. I gave tried each of these suggested fixes several times and nothing works. I'm going crazy as I am working at home and really, really need this computer to work. I will never do another BIOS update.

If the BIOS Recovery options doesn't work, I suggest you purchase a USB flash drive(8GB or 16GB) at your local Walmart. After you purchase it, please find another computer (local library),download the latest BIOS update from your Dell Product Support page, and then save it to a bootable USB Flash Drive. Please follow instructions in link below:

EDIT:

I'm going to try this one...on my way to buy USB and go to library. Fingers crossed.

Tried this one...didn't work.

I am having the same issue on my Dell XPS 15 9550. After I installed BIOS 1.2.19 (after I was prompted to do so by Dell Support Assist pop up) I now get the No bootable devices found. I am working with @DellCares via Twitter. I will let you know if they come up with a fix.

Would be really great except my library doesn't let me download applications to their hard drive so I can create a bootable USB. I asked a friend to let me use her desktop but it is a Mac and I couldn't translate the directions to macspeak. Waiting to hear back from another friend with a PC. Meanwhile tick-tock. Not cool, Dell. Not cool.

Please do... day 2 with nothing that works other than bundling it up and sending away for a week. That is a weeks worth of work lost...grrr.  Because I download a Dell update
