Although I configured windows startup and recovery settings exactly as you showed me in your screenshot above, the minidump folder is still empty after two BSOD.
Open Windows File Explorer
Navigate to C:\Windows\Minidump
Zip up the contents of that folder
Upload the zip file to the Cloud (OneDrive for business, DropBox . . . etc.)
Then post a link here to the zip file, so we can take a look for you . . .
