Seems a lot of people like to save hard-disk space using NTFS compression, but accidently also compresses the boot manager files so it fails to boot.

Have added some articles about the Vista Boot Manager and system recovery:

• Configuration of the boot manager entries which also includes two free utilities that are easier to use than BCDEdit.
• Windows Recovery Environment which replaces the Recovery Console known from Windows 2000/XP/2003.
• Boot Manager is missing or compressed which describes some solutions for these errors.
