I have such a mistake No Bootable Device Found
I have an OptiPlex 9020 computer and I want to turn on uefi with safe boot on it, but when I turn on these 2 I get the No Bootable Device Found error, everything that was supposed to be turned on is on and I have no idea,
which is why it pops up

To send a private note, click on the envelope icon next to your avatar at the top of the page, which should take you here. (I can't seem to find the envelope or use the private notes page from a mobile browser.)
I suspect your problem is that your boot drive is partitioned in MBR format, rather than the GPT format which booting in UEFI mode requires. Check this article for instructions on how to check to ensure this is the case, and how to convert your drive from MBR to GPT with Windows' "mbr2gpt" tool. A few notes/caveats:
