RE: [mssms] UEFI systems - multiple Windows Boot Loader entries
Hi there Aaron - that is kind of where I am looking right now. 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.

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
RE: [mssms] UEFI systems - multiple Windows Boot Loader entries
I don't think it would be too difficult with PowerShell. I use PowerShell to
run the command on my build and capture and select the strings I want for
inventory purposes. You just have to parse a little more text and go from
there. I think the most difficult part would be determining which heading you
are under, {current} {default} etc.
write-output --
write-output Verify startup options
write-output --
$recovery = bcdedit /enum
if (($recovery | select-string recoveryenabled) -like recoveryenabled*no) {
write-output SUCCESS: Recovery is disabled!`n
} else {
write-warning Recovery is still enabled!
write-output `n
}
if (($recovery | select-string bootstatuspolicy) -eq IgnoreAllFailures) {
write-output SUCCESS: Failures ignored!`n
} else {
write-warning Failures not ignored!
write-output `n
}

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

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?

Hi there Aaron - that is kind of where I am looking right now. 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.

It can occur with a Hyper-V Gen2 VM or Surface as well. 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.
