Yesterday I was watching a movie. Today no bootable devices found.

Not sure whether this was due to 1. An update that may have gone askew, or 2. An app that was suggested by /u/DellCares (on reddit) called superfix causing an issue. The app was a means to fix microphone issues I was having, but wasn't working properly.

Now I've been scouting around and no one seems to have had errors recently... Though, there was a similar issue for 9550s: https://amp.reddit.com/r/Dell/comments/50bglj/xps_15_9550_no_bootable_devices_found_after_bios/ In which the fix was going into BIOS and finding bootx64.efi, of which I cannot find (it does not appear on the list). So this may have been deleted.

Anyone have a fix?

• I've messed with secure boot, legacy boot and the boot sequence
• no errors in diagnostics
