This happened to me on my daughters Lenovo. Got a windows update overnight. Updated while traveling in the car. Wouldn’t boot. Apparently the BIOS updated and there was no fix. Had to send gor a replacement under warranty. Sent it off, took 8 weeks to get it back. Wasn’t even the same serial number, just a replacement with no sdd.
My tinfoil hat theory: this is going to people who wish to target various groups.
