Symptoms and description
This Error is linked to the error messages, alerts, warnings, and symptoms listed below.
Symptom 1: The “Bootmgr is corrupt” error screen appears on starting
When a computer is powered on, the BIOS selects a bootable hard drive and then executes code stored in the MBR at the hard drive’s beginning. The bootsector is loaded from the active partition by the MBR code. This bootsector code is responsible for loading the BOOTMGR file, which is used to load the operating system kernel and launch Windows on newer systems. This file is normally found in the active partition’s root directory on the first boot drive. The boot process is halted, and the “BOOTMGR is corrupt” error screen occurs if the bootsector detects that the BOOTMGR file is damaged.
