Can’t get an HP 8200 Elite Small Form Factor to boot from USB. It’s done so in the past & the USB boot drive works in a different machine (HP 8440p laptop).
Have tried upgrading BIOS (from 2.09 to 2.15a, then back to 2.14a) with no luck.
USB drive appears in BIOS “Device Configuration” list, but not in “Boot Order”. USB Hard Drive is set highest in the BIOS “Boot Order” list.
What simple, obvious thing am I missing here?
Answer
The 8200 uses UEFI, not traditional BIOS; in the Boot Order menu, there are submenus titled “EFI Boot Sources” and “Legacy Boot Sources”.
One method for USB booting this machine is to disable the EFI boot sources and enable USB Floppy/CD under Legacy boot sources; we’re using the Legacy Boot option to set PXE network boot. It should also possible with an EFI-configured USB drive, but I’ve not tested that.
