Why not boot OS from USB drive?

Hello.
Installed it on a USB flash drive windows 10. To try out on his PC, everything worked properly.
Decided to try in school, but not out. There is too windows 10 ltsb. I (shift) reset the system select the tab UEFI... there are several boot options, choose your USB flash drive. After, I press the DEL key, you receive the BIOS looks like this: 1508181555291.jpg on the bottom right, I can drag and drop your flash drive in the first place and close, save. System as if the stick is loaded (preloader is spinning), but again loaded the "native" OS. Tried Linux download, over and windows 10 no. Tell me, please, how do I load your OS in this situation?

Write down the best with Rufus
this will really help? Why not AOMEI Partition? - Dallin commented on June 8th 19 at 17:20

Nothing appears. Just choose the image and the bios or uefi - Mandy62 commented on June 8th 19 at 17:29

It was like that on the ASrock settings UEFI fast boot is enabled, ignoring all the flashes, maybe it
Linux turned to run, not win10 - Dallin commented on June 8th 19 at 17:22
