Hi,   I was referring to F11 Boot menu. I found a youtube video showing something the same boot menu, but the person installed the USB in the mainboard port. You need not install the same. [URL]
I have recently acquired a R430.  I "repurposed" the system via the LCM then updated all the firmware on 3/29/2020.  When configured to boot from BIOS the available boot devices are:  CD ROM, Drive C, PXE boot.  USB does not show up as a boot option.  When configured to boot via UEFI (which is what I want) the available boot devices are CD ROM & PXE boot.  Neither USB or Drive C is listed as a boot option. USB is configured in the BIOS in the "Integrated Devices Settings" as "All Ports On."  The PERC H730 is configured with a virtual drive and is visible in BIOS.  It should also be available in UEFI.  Any ideas on what could be wrong?
