I want to use my Windows 10 Pro Dell desktop computer to make a bootable cd/dvd so I can update the BIOS on my HP 8470p laptop computer that has no HDD installed but does have a working cd/dvd drive. I downloaded the latest BIOS update files from HP. I have an old version of Roxio on my Dell which has the option to make the cd/dvd bootable. When I try to burn a disc using the "make disc bootable" option, it asks me where the required boot files are located.This is where I am stuck.

Where do I find the required files to make a cd/dvd bootable?

Another option is to make a USB flashdrive bootable. But I have no idea of how to do that. Do you? I put the BIOS update files on a USB flashdrive per HP instructions but it did not boot.
