I have a Sony Vaio Pro 13, which came pre-installed with Windows 8 and the Vaio Care/Rescue Utility. My goal was to make it dual-bootable to Ubuntu 12.04 as well. As it turns out, the Ubuntu install worked, but it is not bootable, and after a few runs of boot-repair, it does not boot to Windows 8 and I cannot access the recovery partition that is built into the laptop. The only thing I can do is boot from my LiveUSB (with try ubuntu) The last boot-repair gave me this : http://paste.ubuntu.com/6464375 and after I tried to recover Windows this http://paste.ubuntu.com/6469950

Your problem is that boot-repair did not update GRUB2 correctly. Luckily, there is a very easy fix for this. Here's what you can do:
- Boot to Ubuntu.
- Press Ctrl+Alt+T To start a Terminal emulator.
- Type
sudo update-gruband press Enter. - Once the command is finished, reboot.
You should now see Windows 8 as an option in your boot menu. Good luck and have fun with Ubuntu!

Unfortunately incorrect answer, as Boot-Repair already did an
update-grub(seeline 931of Hugo's log paste.ubuntu.com/6464375). Line 938 you can see that there is already aWindows 8 (loader)entry in the GRUB menu. Nov 24, 2013 at 21:16 -
I've had this same problem.
boot-repairoften says it runsupdate-grub, but often that causes problems. Doing it from Ubuntu itself fixes that (I know from experience).– DillmoNov 24, 2013 at 22:04 -
Never seen any report about such issue :) If you can reproduce, please could you create a bug report HERE ? (please indicate the Boot-Repair log, and the output of update-grub) Nov 25, 2013 at 18:16
Run Boot-Repair again, but this time answer No to the question Do you want to activate [Backup and rename Windows EFI files]. Then reboot, you should be able to access both Windows and Ubuntu via the BIOS (indeed UEFI firmware).
