I guess it is not possible.. Found this article on vendor site
"- Can the JetFlash be used as a bootable flash drive?"
"JetFlash series aims at being a portable storage device and not as a
bootable drive. No exclusive software tool is provided either."

I'm having problems with USB boot from Transcend JetFlash 620 drive 32GB.
SeaBIOS doesn't see it as boot device. I suppose the problem is in
SecureDrive technology that is used on this device. I tried to remove it
with "CD-ROM Remover_v22.214.171.124" tool that I've found. It removed CD partition
from OS, but SeaBIOS still can't see flash drive as boot device.
Does someone know how to solve this issue?
