[SOLVED] Intel NUC i5-5250U will not boot from USB

My Intel NUC bios recognises the existence of the USB drive, but it will not boot from it -- after a while it gives me the Linix Mint installed on it. What should I be doing?

Boot to bios and see if the usb shows up under hard drive choice. Then move it up in bios order. Then boot to hard drive maybe.

I assume you have tested this drive on some other similar unit maybe.

Kind of doubt a nuc has uefi secure boot but maybe check bios settings. Latest mint should boot to uefi but may not have secure boot loaded. There is a lot going on with uefi too so you may more easily use legacy or csm.

Many thanks, jefro, for your suggestions. They prompted me to check whether the partition of the USB drive had its boot flag set. It hadn't, and so I set it. The BIOS itself was quite awkward to set as you suggested, as sometimes it would show my two hard drives as UEFI (without boot) and no legacy drives at all, and sometimes as legacy, along with the USB drive seemingly regardless of how I had saved it. Eventually I put his last at the top and got it to stick, and then the machine would boot from the USB!
