I have had no issues with the install ISO using dd from linux to copy
directly to the device. Something like:
dd if=./<name.iso> of=/dev/sd<letter> bs=4M status=progress
Where 'of=' is the device // make sure NOT to use a separate partition
(so /dev/sdb and not /dev/sdb1, but the whole device when copying the
install isos.
If you are trying to do something else (create a bootable actual
partition that runs from usb .. that should also be possible, but harder :)
