Abstract

An emergency boot directory, containing a back-up copy of a primary operating system, is maintained in a protected, hidden subdirectory hierarchy during normal computer operations. A bootable media, which may be a removable media, contains bootstrap code operative to load and run the back-up operating system, if the primary operating system fails to boot and run. A file system filter driver hides and protects the emergency boot directory by intercepting file or data access and directory entry enumeration requests. The filter fails access requests directed to the emergency boot directory, and edits the results of enumeration requests to remove references to the emergency boot directory. The protected, hidden emergency boot directory can be located and maintained within an existing main storage area and does not depend on hidden attributes of secondary storage areas such as separate disk partitions or file systems.
