Hi there Aaron
Thanks for the note. No, this really is just on the test systems which we have but I'd like to leave the deployment tidy if I can Jason From: [email protected] [mailto:[email protected]] On Behalf Of Aaron Czechowski Sent: 17 December 2013 18:26 To: [email protected] Subject: RE: [mssms] UEFI systems - multiple Windows Boot Loader entries Hi Jason - I'm unfortunately not too knowledgeable on that myself. I know a support engineer was looking into the same thing, but also got hung up with how to automate it. Is this something you see frequently on deployed end-user systems, or is it just during testing?

We could of course query the BIOS using manufacturer code but as BCDEDIT is generic then it would seem to make sense to use this tool. The problem then of course is that any solution seems to revolve around creating a text file, parsing it and then doing something with the result. It would be nice to find some more intelligent way of working with this data. I know that someone did mention that boot methods change on Surface devices and I wonder what form that takes? We have had some systems that seemed to boot back into Legacy but these were HP desktops with scores (yes, really) of Windows Boot Loader references.

Some investigation occurred and I think the outcome was an issue with Windows setup. One customer raised performance concerns, but I think that's anecdotal and not proven to be related. I think the general belief is that this should not cause any serious issues. Outside of a test environment where a specific system is refreshed multiple times, I would not expect to see this done more than once or twice on a given system. As you said below, easy enough to script in the task sequence, but I think the challenge is determining which ones to whack.

I know this is a HP related issue rather than CM but any suggestions for removing these entries please? The usual suspects of reload defaults and disable & enable UEFI do not help Jason
