This is the second time i refer to your video, it is really helpful. For real, i went through other videos with the same title but they have no idea what they r talking about. Well done mate, well done.

The perfect Tutorial.
This came in handy because Microsoft no longer offer the Windows 10 -1511 Build. This build allows you to install the full version then active your computer using your Win 7/8 key. No need to install one of those versions then upgrade to 10. Lucky thing I created a USB version when I had the chance to on their site.

Very helpful - exactly what I was looking for but was struggling to find until now. Thank you for producing & sharing

This method ONLY works IF the USB you are copying had that etfs file, which many don't. So, it's great if you are using a M$ disk of some sort, but it doesn't work on the vast majority of disks. there are dozens of videos on YT showing this same method and ALL use an M$ installation disk, because it doesn't work on most others.

Great work. It's took me a while, to find this . Usually is other way around, from CD to USB, but I still have older PC, and the bootable option is not available in BIOS from USB, only CD ROM . Most of the software including windows 10 is on USB . So I was happy that this program works and make my bootable CD from USB .

Thank you! Worked perfectly. So many other tutorials made this seem far more complicated than it actually was.

I've watched already so many videos trying to learn how to do that but finally now I know how
Thanks a lot !
By the way would that work if the source USB contains more than one petition?
And all partitions are necessary for the os to boot up!
