Description and Symptoms<\/span><\/h3>\n

The error messages, alerts, warnings, and symptoms below are tied to this error.<\/p>\n

Symptom 1: “Bootmgr is corrupt” error screen on startup<\/h3>\n

When a computer is turned on, the BIOS picks an eligible, bootable hard drive and then calls code stored in the MBR at the start of that hard drive. That MBR code in turn loads the bootsector from the active partition. On newer systems, this bootsector code is tasked with loading the\u00a0BOOTMGR\u00a0file, which is\u00a0used to load the operating system kernel and start up Windows. This file is usually\u00a0located in the root directory of the active partition on the first boot drive. However, if the bootsector detects that the BOOTMGR\u00a0file is damaged, then the boot process halts and\u00a0the \u201cBOOTMGR is corrupt\u201d error screen appears.<\/p>\n
