Windows 7 USB Download tool says “the selected file is not a valid iso file”

I wanted to make a bootable USB stick with the HP’s OEM Windows 7 Professional, but the Windows 7 USB Download tool tought otherwise and didn’t want to accept the HP’s OEM ISO with “the selected file is not a valid iso file. please select a valid ISO file and try again” urgh.

There is a trick however to make the Download tool accept that ISO, here it is:

Download “PowerISO”, you’ll need the full version because the free version doesn’t like ISO files larger than 300MB. Open your ISO in PowerISO and go to file and then properties. Select “UDF” and save your ISO, the saving process shouldn’t take more than a couple of minutes. Use the latter ISO in the Windows 7 USB Download tool et tadaah!
