That is a huge pain, as the CMOS batteries on those precisions are an INCREDIBLE pain to get at and remove from their holders. I dunno why Dell put those big plastic tabs over the top of the cell, completely unnecessary, it's like it's clamped in there and I worry that forcing it will break them. >:/
This is a Windows 10 Pro system, and the Windows Boot Manager is the first and only option in the UEFI boot settings. I will check BCDEdit, though, I suppose that's a possibility? But it still doesn't make sense why it would say "No bootable devices found", only to then... you know, BOOT, after I press F1.
I'm a little hard-pressed to think it's something on the OS-side, since the UEFI hooks into the EFI file and that's that. It doesn't know to do anything else. So it's clearly doing the following:
Looks for bootable devices
Doesn't find any, asks user what to do
User presses F1 to retry boot
Machine boots
Doesn't make any sense to me. I have also done the following:
Run Dell's PSA diagnostics. All hardware passed.
Run the Crucial Storage Executive software (for the Crucial MX500 SSD that I'm using as the primary boot drive). The device was reported to be in good health.
Run: bootrec /fixmbr - to repair the Windows master boot record. Command completed successfully, no change.
Run: sfc /scannow - to validate Windows integrity. It passed.
Run: dism /online /cleanup-image /scanhealth - to validate Windows integrity. It passed.
I suppose I should run a chkdsk C: /r, but I'm not sure what else I can do at this point.
I suspect that you may have more than one drive in your system and the EFI boot partition was on the second drive (which is not a OS drive). Verify if that was the case.
I do have another drive in the system, but it does not have a bootable partition or anything. I will try booting it unplugged to verify if this is the culprit, I may just need to wipe it.

Not knowing exactly how old your system might be, assuming over 5 years anyway, it is possible the CMOS battery needs to be replaced.

Hello, if you use Windows, you may want to set Windows Boot Manager as first boot in BIOS settings. Or use BCDEdit for Editing Boot Options
