Hello
I want to write a relevance to MultiOS Check.
run → msconfig → Boot
If you look below, in case of MultiOS, two OSs are displayed as shown in the attached picture.
MultiOS in case of 2 or more
If there is only one, I want to create a column that is expressed in the console expressing SingOS.
How should I write relevance?
I need help
You’d need an action to run something like ‘bcdedit.exe /enum’, output that to a file, and read the resulting file in an Analysis.
It’s more complicated than I thought
But I think it is too much work to create and read files for the current bigfixclients.
Is there another way?
Careful what you ask for!

This will produce a dump (in JSON format) of the BCD database loaded into the registry upon boot.
Applying

to the above should give you what you want.
