Find a solution to the problem. On Windows Vista, Windows 7, Windows 8, Windows 8.1, or Windows 10, Bootmgr is compressed.

Symptoms and Description

This Error is linked to the error messages, alerts, warnings, and symptoms listed below.

Symptom 1: The error screen “Bootmgr is compressed” 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 compressed” error screen occurs if the bootsector detects that the BOOTMGR file is compressed using built-in Windows file compression.

Cause 1: BOOTMGR is compressed

File compression is a function that allows users to minimize the size of files, folders, and programs to save space on their hard drives. The BOOTMGR file, which is an important aspect of the booting process, should not be compressed because the system bootsector code lacks the capacity to decompress files on its own.
