And then, the BIOS scans the hard disk master boot record (MBR), which loads an essential file into main memory called WINLOAD.EXE, which kicks off the start-up progress by loading the NTOSKRNL.EXE and HAL. Then, Windows 10 starts up and performs tasks such as initializing hardware like mouse and keyboard and reading the Windows Registry and user profile.

Info: A component of the operating system has expired.
This could be a serous error, but don’t panic, you can fix the error with Startup Repair or BootRec Commands.
