copy all the files from that folder onto the USB stick.

format USB stick with FAT-32 filesystem.erase USB stick and create MBR (master boot record).So the first two steps are the same, then Windows and Linux have separate procedure. For generic Linux installation ISOs this procedure would be simpler. Windows 10 is a very specific bootable media, so the process is a bit involved. All of these need to be done in the Terminal app. Here are the steps I had to take on my MacBook, originally procedure was written in macOS High Sierra, but I tested it in MacOS Mojave 10.14.2 as well. This approach will be simpler for any other ISO image like Ubuntu or CentOS, so there’s a separate Steps 3-5 for them at the end of the post.

Since it’s possible to boot and install Windows 10 from USB, that’s what I decided to do: download Window 10 ISO and burn it one of the USB sticks I have. I needed to reinstall one of my Windows PCs at home recently, and realised that I only have Windows 7 DVDs, but no Windows 10s.
