Update, new problem:
I disabled secure boot and for some reason wasnt hit with the read-only error when writing to /EFI/Boot/. Following these steps http://www.hackourlife.com/sony-vaio...-04-dual-boot/ I was able to load grub,
Thats the good news. The BAD news is that in order to get it to work i had to overwrite "EFI/Microsoft/Boot/bootmgfw.efi" with grubx64.efi. I made a backup of the original file but its just gone. I dont know if i failed to copy it or if it was overwritten somehow but its lost now anyways.
Without it windows wont boot. is there anyway to to fix this? or will i have to reinstall windows to get the original bootloader restored?

Hi, Ive been trying to set up ubuntu (12.10 64bit) dual boot with windows8 on my sony vaio laptop (SVS1312K3EW) without much luck.
Ive followed these instructions: https://help.ubuntu.com/community/UEFI
I could not find any options in my bios interface to disable QuickBoot/FastBoot or Intel Smart Response (step 2) so i did not perform that step.
After rebooting, my laptop will not load grub but just boot straight into windows8. Ive run the boot-repair tool (http://paste.ubuntu.com/5643853/) but it wasnt able to fix it.
I tried to move the grub efi file to EFI/Boot but i was hit with an error like this one:
This bugreport describes it further: https://bugs.launchpad.net/ubuntu/+s...2/+bug/1091477
I have yet to try the workaround posted there though.
Ill continue to tinker with it but im hoping someone has already come up with a fix.
