I would like to install Ubuntu with a USB which was prepared with UUI, but it says "No bootable device found. Insert a bootable device and try again." I tried the exact same thing before on my previous laptop and it worked just fine. My laptop is an HP 15 Notebook PC. My previous laptop was also an HP 15 Notebook PC, but had lower specifications. I checked and my laptop is UEFI just like my previous one. Any and all help is appreciated.
