Odd one. Tried to create a bootable W10 usb and on both my pc and laptop it caused them to bsod when trying to create it. I presume it works just the same if i grab the iso? Think i'll go that route and use rufus. Bit odd, bsods i would presume indicate a driver issue or some sort of conflict - just bizarre it happened on both pc and laptop.
It worked perfectly for me when used it it a couple of times recently. Maybe try a different USB drive if that is the common thing when trying to create (and failing) on two totally separate systems?
Gah it was a long day yesterday. Yeah thanks of course, completely didn't think of that... Just wait till later when i come back asking for help in tying my shoelaces. Edit: it probably didn't like the fact that usb had previously had an old linux mint iso on it
