I had the same problem and I created the disk right from the 760 PC. It came up with the same issues of "Could not get network adapters." after the networking was started. I went to Dell's web site and downloaded the Windows 7 32 bit driver for the intel drivers and put it on a flash drive and carried it to the 760 PC while the bootable BESR interface was up. I then opened up a command prompt and installed the drivers while inside of the boot disk. It then was able to get an IP address and I was able to map a drive to my recovery location.
