Hi,

a file system driver that I've developend and signed by MS is beign refused by at Win10 startup processof.

ntbtlog.txt:

...

BOOTLOG_NOT_LOADED \SystemRoot\System32\drivers\myfs.sys

...

I have applied the signtool to verify the chain of signatures - all good.

Where can I find the reason for the failure?
