Hello,

I tried to intall ubuntu 12.10 64bit (usb) on my new Sony T series. I disabled secure boot and followed instuctions from: https://help.ubuntu.com/community/UEFI
I can boot to ubuntu but windows 8 will not boot and I just get the Invalid EFI file path" error. (I think Bug #1024383) As the instructions said I booted to live usb again and ran disk-repair (paste.ubuntu/1406514). However it is still giving me the same error. So I used the windows recovery to repair boot and i can now boot into windows 8 and it works fine. I now have a raw partition where i had installed ubuntu originally. Any help would be much appriciated. Thank you.
