This package provides the HP UEFI Support Environment version 220.127.116.11 in supported models that are running a supported operating system.
UEFI and Custom Imaging
The HP PC Hardware Diagnostics UEFI must be run from a FAT or FAT32 partition with a partition name of "HP_TOOLS" or "EFI". This installer will give you the option to install to the HDD or a USB drive. If you install to the HDD and the HP_TOOLS or EFI partition is not present, the installer will prompt you to create the partition. If you install to a USB drive, the installer will rename the partition on the USB drive to HP_TOOLS. If you use a custom image, you can create the HP_TOOLS partition manually with type FAT32 and make the partition name HP_TOOLS.
Caution - The HP_TOOLS partition is not protected and can therefore be deleted. - Backing up the computer using the Windows® Complete PC and other backup software does not back up the HP_TOOLS partition.
For these reasons, HP recommends that you do not place additional data on the HP_TOOLS or EFI partition. 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.
