gPXE has not been maintained for several years.  Please upgrade to iPXE, which 
is the replacement for gPXE.

You won't be able to open the .usb image, since it doesn't contain a 
filesystem.  It's a raw disk image; you need to transfer it to the USB key 
using dd (or equivalent).  Be aware that this will erase all existing content 
of the USB key.
