I just installed Ubuntu 13.10 on my new Vaio Pro 13, disabled safe mode, but used UEFI and not legacy mode. I did an encrypted LVM installation and erased the complete SSD. It booted just fine from USB, but after installation it doesn't boot. The Vaio failed boot screen appears. I then tried this advice here: 13.10 on vaio pro with UEFI sadly it fails for me with "/usr/sbin/grub-probe: error: failed to get canonical path of /cow." I then tried mounted the encrypted partition with Nautilus and tried this: Cannot update grub with paramters on live USB With /dev/sda2 and then to install GRUB to /dev/sda. Didn't succeed and warned me that the "GPT partition label contains no BIOS Boot Partition; embedding won't be possible" What do i have to do, go fix GRUB and be able to boot my finished install? Here's my Boot Repair Log: http://paste.ubuntu.com/6386598/ I would really appreciate any help, I'm so happy to finally be able to ditch my big fat Macbook Pro and use Ubuntu on my new, light Vaio Pro, if only I could fix GRUB. best, x
