Nice to see that somebody has picked this report up. In the meantime, newer version of the kernel shipped with saucy support the network card of the SONY Vaio Pro 13. I guess this has defused the issue for network connected machines. Also, I have been able to dual boot in UEFI.
What worked for me two months ago (in the meantime, things might have improved): After installation, boot with a LiveCD and execute the following commands (assuming the EFI partition is /dev/sda1) sudo su mount /dev/sda1 /mnt cd /mnt/EFI cp -a ubuntu Boot cd Boot mv grubx64.efi bootx64.efi -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1201101 Title: grub-efi is a must for a functional LiveCD experience To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lubuntu-meta/+bug/1201101/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
