How To Fix BOOTMGR Is Compressed Error Message

 
Windows 7

Boot into the System Recovery Options using the preinstalled Advanced Boot Options or a Vista/7 installation/recovery DVD – see the illustrated tutorial at Sevenforums for instructions if required.

• Select ‘Startup Repair’ and wait until the repair attempt completes. If successful you can then restart the computer and Windows may boot up normally.

If the repairs fail and/or the computer does not restart into Windows normally, proceed as follows.

• Boot into the System Recovery Options again but this time select ‘Command Prompt’ instead of startup repair – this will take you to a windows command prompt.

[Note: if using RAID for multiple hard drives you may not see your version of Windows listed in System Recovery Options, during the loading of the recovery process. In this case you would need to press 'Load Drivers' and browse to your RAID drivers so that your version of Windows can be listed]

• Type bootrec /fixmbr and press Enter. Press Y to proceed

• Type bootrec /fixboot and press Enter. Press Y to proceed

• Type bootrec /rebuildbcd and press Enter. Press Y to proceed

• Type Exit and press Enter to restart the computer.

The BOOTMGR is compressed error message should not appear and Windows should boot normally.
