I've replaced my HDD by a SDD on my Zenbook Prime and am trying to install only Ubuntu 14.04. Before, I installed Ubuntu on the HDD which was already containing Windows 7, and everything worked great. I've made a GTP partition table on my SSD and created 3 partitions, a boot efi one, / and /home. When I boot, I can see grub but then after grub is complaining that it cannot find the disk by uuid. Boot-repair doesn't work. I've tried installing letting Ubuntu do the partitionning, same problem. I've tried disabling secure boot (which is named "anti-theft in my BIOS...) and installed in legacy mode, same problem too.
/dev/sdb is my live Ubuntu on an USB key.
Here is boot-repair log: http://paste.ubuntu.com/7338302/ idea why my disk is not found?
Edit: I've changed the GPT table to a MBR (msdos in parted) one and created 2 partitions: / and /home. The problem is still the same, it cannot find the disk by uuid. I've launched boot-repair, and this time, it worked, but the problem is still here. Here is the new pastebin: http://paste.ubuntu.com/7340850/
