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.
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!
