If you have or can access another computer that isn't a mac, I'd check the drive on that computer to see if it also fails. If it fails, you got a bad drive. Flash drives can come from the factory and either work temporarily or not at all. Another possibility may be the usb port to load the drive is bad so maybe try a different port. Have you ever booted a flash drive on that apple computer in the past? If no, then you're in new territory. Apple uses a different disk format and I don't know how this works with flash drives or if it's not relevant here. If you downloaded the sha512 file you'll have to fix its format a string of ' /out' is in that file and needs to be removed. Then you can check the iso integrity with sha512sum -c Jenux-xxx.iso.sha512. If you can access the flash drive not booting it, an integrity check of the iso on that flash drive after you copy the corrected .sha512 file to the flash drive could be informative.
