Have just taken delivery of an Intel NUC8i5BEK, installed RAM & SSD. A USB stick with: $ dd if=~/Downloads/devuan_beowulf_3.0.0_i386_desktop-live.iso of=/dev/sdb bs=512k looks good mounted on another host, but doesn't boot in the NUC.
On power-up or Ctl-Alt-Del, the NUC reads the USB twice (LED on the stick flashes), but then reports "A bootable device has not been detected." I've gone into the BIOS, and in the Boot Order tab, hit Advanced, then in Boot Configuration tab set "Boot USB Devices First". F10 to save. That gives a Boot Devices list below with a greyed out "Internal UEFI Shell", followed by "USB", then the others below that. Looks good, but returning to the adjacent Boot Priority tab shows: UEFI Boot Priority Legacy Boot Priority ------------------------ --------------------------- UEFI Boot Legacy Boot Boot Drive Order Boot Drive Order "No Boot Drive" UEFI LAN: PXE IP4 ... UEFI LAN: PXE IP6 ... and the Boot Order tab seen on entry to the BIOS shows the same. From that I infer that legacy boot from USB is not a BIOS config option, and that the Boot Configuration tab setting isn't recognised in the Boot Priority tab's UEFI column. (At least for display, since the USB is accessed twice during boot.) Can anyone spread a sprinkle of enlightenment on this apparent impasse? Erik
