UPDATE: If I disable Bluetooth in BIOS, I can now use Fast Boot option. Go figure?
Were you experiencing this issue with previous BIOS version?
Probably BIOS version: 0037
Go to the first page when you opend the bios.
Dubb. Click on the option uefi ip4..........
And your nuc whil start in fastboot.
i never tried the fast boot with any previous version of BIOS since the NUC was brand new and I updated to v41 even before installing the OS. It's almost a moot point, as I now let my NUC go into S3 sleep, from which it awakens almost instantly. According to my Kill-A-Watt, the skull canyon shows a power draw jumping between 0 and 3 watts during S3 sleep.
