Zed, don't know if this helps but when I put Debian on my L440 I first
had to do some futzing around in Windows10 to prize its cold dead
clutch (aka Secure Boot) off the boot order before I could get into
the BIOS.    
I can't recall if it hid USB from the BIOS options.

You may need to change the boot from UEFI to Legacy - 
I've just looked at my L440 BIOS and I see it's now set as:
    UEFI/Legacy Boot  -  [Both]
        -- UEFI/Legacy Boot Priority	[Legacy First]

and   Boot Order Lock			[Disabled]
		(Enabled  would lock the boot order)         

There's a Lenovo page on USB boot sequence here:
and a Microsoft page on how to disable Secure Boot here:
