Hi Splinx,

Is using bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS the command-line way of getting into the 'normal' startup-options => disable integrity checks??

(I guess so, just curious)

OK: did the upgrade using bcdedit.

I got a couple of hickups:
TESTSIGNING ON didn't work at first because 'secure boot' was on. You can disable this BIOS feature (Press F2 right at startup on a Dell XPS13)
The “unsupported driver” – “Intel USB 3.0 Root hub” device wasn't located at the Universal Serial Bus Controller section but in its own 'unknown devices' area

The rest of the process was pretty straight-forward.

Thanks!
