I do not believe it is possible to burn the ISO into a UEFI. You need to go into your BIOS menu and switch the booting option from UEFI to CSM.
This should solve your issue.
Have you tried to burn your ISO through your Mint terminal? Try this:
Code:
1.Plug in your USB device to your Linux computer’s USB port.
2.Verify the device path of your USB storage with
dmesg
Proceed to (carefully!) image the Kali ISO file on the USB device:
Code:
dd if=kali.iso of=/dev/sdb bs=512k
Hope this helps in any way.
