JohnK,
Glad to hear that worked for you.
Laszlo,
That fix applies to UEFI booting any 32-bit device which includes HP Elitepads, but is not limited to them. If you run into any issues you'll want to apply the 228A patch, but SP1 is not far off so I can understand waiting as well. Let us know if you have any other problems.
Thanks,
Bryce.
