HP SUM and SPP Boot environment
Beginning with HP SUM 6.2.0 and SPP 2014.02.0, the HPE USB Key Utility no longer supports multi-boot setups on a single device. The HP SUM and SPP ISOs contain signed parts to work with the UEFI bootloader. This change no longer allows for multi-boot setups on a single device, such as a USB key.
The following sections discuss deployment from HP SUM. For more information on planning an update, see the HP SUM Best Practices Planning and Implementation Guides available on the HPE website:
