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 parameters 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
