The same problem found using Lenovo Z480 and Z580 (my is Z580A) with Ubuntu 12.04 and 12.10. See http://askubuntu.com/questions/235942/ubuntu-12-04-and-12-10-fails-to-boot-after-usb-1-1-4 To workaround they use an old version of kernel: kernel 3.2.0-29-generic. The same problem with Z580 found at https://answers.launchpad.net/ubuntu/+source/unity/+question/215279 They found a workaround to remove a battery during boot with AC connection. I did not try it. There is not so good idea for me but may be a key to solve a problem. Also the same problem reported at http://askubuntu.com/questions/225538/uefi-boot-failure-hang-after-printing-usb-information I try both variant of booting: with and without EFI. No difference. I replaced a memory from 2+4 GB to 8 GB (Kingston 2x4GB KIT). The regularity of unsuccessful boots does not change.
