A method for registering and initiating a pre-boot environment for enabling partitions. The method provides a basic input output system (CIOS) with an application program interface (API) that accesses a Logical Clock Address (LCA) sector number when a boot configuration flag is set, the LCA sector number stores an operating environment manager which then boots the information handling system to an appropriate partition.

Information handling system boot with an operating system initiated by a BIOS maintains consistency of storage device numbering order between the BIOS and the operating system by branding BIOS storage device configuration information on the storage devices for subsequent use by the operating system. A branding module in a Linux operating system retrieves BIOS hard disc drive configuration information from the BIOS during real mode of the boot which allows operating system access to the BIOS, and stores the hard disc drive information on its associated hard disc drive. A branding retrieval module in the Linux operating system retrieves the configuration information from each respective hard disc drive during a protected mode of the boot which does not allow operating system access to the BIOS, and applies the configuration information to the operating system for consistency with the BIOS.
