While I'm awaiting official tech support for iso stick not booting, maybe someone has suggestions. Because SM works I have tried all diagnostics I know in W itself. This does not fit strict def of "boot problem" imo & I was not surprised bootrec passes tests. I almost thought unique problem, never reported, but it was reported briefly by someone here, then no follow up. Since I have SM maybe I could access ER tools on stick, but I would be working from within Windows rather than outside it. Is this doable?
