I've downloaded windows 7 via an official link and so now I have the .ISO file on my computer. However, I need to install this on to my new PC using a USB as the new PC doesn't have a disk drive and I cannot remove the one from this computer. I've seen various videos and various ways but there doesn't seem to be one for my particular situation. I have the .ISO file and need to put it so I can boot into my USB on my new PC and it will install. Help would be appreciated
