What Events Can Occur During Bootmgr’s Role in Startup

The bootmgr (boot manager) is an essential component of the Windows operating system that plays a crucial role during startup. Its primary function is to locate the operating system’s boot files, load them into memory, and initiate the boot process. While bootmgr is a reliable component, certain events can occur during its role in startup that may lead to issues. In this article, we will explore some of these events and provide solutions to common problems associated with bootmgr.

1. Bootmgr is missing: This error message indicates that the bootmgr file is either corrupted, deleted, or misplaced. To resolve this issue, you can use the Windows installation disc to repair the startup.

2. Bootmgr is compressed: If the bootmgr file is compressed, the system cannot access it during startup. You can fix this problem by booting from the Windows installation disc and using the command prompt to decompress the file.
