Bootable vs Data Drives and UEFI BIOS

Since the partitions on a data-storage drive are accessed by the OS and not the BIOS, GPT drives can be used on non-UEFI systems as data-storage drives. These drives cannot, however, be used as boot drives in such systems. The legacy BIOS in

anon-UEFI system cannot find the boot information on a GPT-formatted drive and therefore cannot complete the boot process into the OS. In using a GPT drive as a data-storage drive, the drive must be formatted using tools that can create GPT partitions.

In order to boot from a GPT-formatted drive, the system must have a UEFI BIOS. UEFI understands how to find the boot information on a GPT drive. In addition, the system must also have a “UEFI aware” OS such as Microsoft Windows 7 ™64-bit. For selected desktops, HP implements the Type 0 BIOS Information data structure (as described in version 2.7 of the SMBIOS specification) to indicate UEFI BIOS support. The BIOS Characteristics Extension Bytes field within this structure has defined a bit that, if set, identifies the system as UEFI compliant. Table 1 describes BIOS Characteristic Extension Byte 2, with Bit 3 identified as the bit for UEFI specification support.
