Hello and welcome pool mate what have you got set as the first boot device in the BIOS and are the USB ports being recognised in there too?

Some system specs would be good too please

You need to be using the black USB 2.0 ports.

What program did you use to put the iso file on the usb stick ?

I would try again with this free program, it never fails.
