How to boot windows using usb if I have windows 10 dvd

[InfamousNavi]

Hey guys, I recently purchased windows 10 64bit and I thought it would come with a product key on the case but it didn't appear to come on it. It ended up being just a dvd enclosed in a case. I don't have a dvd drive on my new pc but I do have usb ports on it and a usb laying around. How can I install Windows 10 using the dvd and the usb with the fact that my new pc doesn't have a dvd drive?

Option 1: Portable disk drive. Plug it in and run it. Works fine. I have several laying around.

Option 2: If you have another computer, you can burn the Windows 10 Update tool from this website to your flash drive and install it through your flash drive. You still need the key, however. You sure it ain't in the box somewhere? If you got it from a third party source like eBay you could've just as easily gotten ripped off.

It came with enclosed in a envelope. The envelope has these things on it : End item PN, Carton NO, COA barcodes. Nothing that says product key. It does have something that resembles a key shape and is 25 characters long. Is that the product key? Could I use the bootable usb I made for windows 10 and use that for it to know I purchased win 10?

When you're installing windows through the USB, there will be an option to enter your key. It's very obvious and is in the same spot as all other windows installations. Minus as well try that 25 digit code. It's probably what you're looking for.
