Download and run the HP System Diagnostics (UEFI) SP from the HP support drivers page 8. The BIOS folder will contain empty Current, New and previous folders. The drive should now be formatted as HP_TOOLS with a Hewlett-Packard folder containing BIOS and BIOSUpdate folders. Select the option to create the HP_TOOLS partition 6. Select the option to install on a USB drive 5. Download and run the BIOS Update Utility (not the BIOS, yet) from the HP support drivers page. Rename the HP_TOOLS partition from the hard disk to something different like HP_TOOLSbak 2. I set up a brand new USB drive as follows: 1. The system BIOS detects the USB drive and HP_TOOLS partition and the BIOS is magically updated. Assuming the USB drive is set up correctly (see below), the BIOS installer sees the HP_TOOLS partition on the USB drive, copies the BIOS and its signature file to the USB drive then runs the winflash installer.

Using Windows 7: Just plug in the USB drive then run the SPnnnnn.exe BIOS file downloaded from the HP support drivers website. For more information, visit: There is little documentation on how to use it, however one member here figured it out. Because the partition is not backed up, corruption or failure of the partition will result in loss of all data on the partition, plus loss of UEFI functionality. For these reasons, HP recommends that you do not place additional data on the UEFI partition. Backing up the computer using the Microsoft Windows Vista Complete PC Backup function does not back up the UEFI partition.

CAUTION: - The UEFI partition is not protected and can therefore be deleted. If you use a custom image, you can create the HP_TOOLS partition manually with type FAT32, and make the volume name HP_TOOLS. If you install to a USB drive, the installer renames the partition on the USB drive to HP_TOOLS. If you install to the HDD and the HP_TOOLS partition is not present, the installer prompts you to create the HP_TOOLS partition. This installer gives you the option to install to the hard disk drive (HDD) or a USB drive. UEFI and Custom Imaging - HP BIOS Update must be run from a FAT or FAT32 partition with a volume name of 'HP_TOOLS'.
