“Caveat: as with any 64 bit Windows OS install to USB drive using this tool, it will give you an error in the fourth phase (making the drive bootable) if you try to run it from a 32 bit system. This is because it can not use/understand the 64 bit bootsect.exe file from the iso.

Easy fix is to extract the bootsect.exe file from a 32 bit Windows ISO and paste the file into the Wibdows 7 USB Download Tool program folder. It will then use the 32 bit version which works just fine to boot the 64 bit OS install.”

Well you can teach an old dog (like me) new tricks.
Or at least remind me of them….

I recently bought a nice new setup for my media centre, but I didn’t want to splash out on another DVD drive when physical media is basically dead – and swapping out a DVD drive from another machine just to install Windows seems like such a waste of time when I could be eating Christmas pudding. While Windows 8 is slated to allow media-less upgrade, today I’ll outline a relatively easy way to make a bootable Windows installation USB drive, without having to download additional software. If your Christmas PC budget didn’t quite stretch to a DVD drive, this is the tutorial for you.

We described a similar method before, but it required a few external utilities. This time I’ll assume you have a working Windows 7 computer with an existing DVD drive somewhere – and a working installation DVD to go with it. You’ll use this machine to format, set up, and copy over the relevant files to a USB stick. You could also do this without a DVD drive from the ISO, but in that case your job would be a whole lot simpler because you could use the official ISO -> USB creator.
