Hi All, Support have sorted me out.
For others - its a simple thing.
You have to make the USB stick bootable using Rufus.exe, which is included in the "additional flies" folder.
Put a blank stick in, and Rufus automatically finds it and fills in the details.
Towards the bottom of the window theres a tickbox, "make bootable using".
The default is FreeDOS, but you need to load the .iso file with the 4.6.1 restore in it here.
When its done you should have a bootable stick with the restore software ready.
Cheers!
