The Recovery Console consists of a minor modification to the boot.ini file, and the addition of a hidden directory on the boot drive. The added directory's name is cmdcons. The change to the boot.ini file is simply the addition of another line providing for a new boot option:
C:\cmdcons\bootsect.dat="Microsoft Windows Recovery console" /cmdcons
This option consists of a fully qualified file name (C:\cmdcons\bootsect.dat), a text description (Microsoft Windows Recovery Console), and a boot option (/cmdcons).
As everyone should be well aware, the Windows XP Boot Manager is able to boot virtually any operating system (assuming that the operating system is compatible with the currently installed file system).
