Windows 10 bootmgr not found error indicates a missing or corrupted boot management utility.
Hello, your Windows 10 upgrade is progressing smoothly at 83%, and the monitor issue you experienced was temporary. The error message about needing to restart via Ctrl+Alt+Del suggests a bootloader problem, which is common during installation. Since your laptop is downloading an image to fix the issue, this should resolve the problem without lasting harm. Just ensure you save any work before rebooting and check for any remaining errors afterward.
The BIOS adjusted which drive gets priority and attempted to locate BOOTMGR on an empty partition. Now it clearly states: Restoring your earlier Windows setup. Probably best to try reinstalling tomorrow morning.
