Dual boot Mint14 x64 and Windows 8 in EFI mode

[dohoangkhiem]

Hi, here is my problem,

I cannot boot to anything after run boot repair.
I'm using a Vaio on UEFI mode, this machine has Windows 8 by default.

I installed Mint 14 x64 from live USB (in EFI mode), but when restart the machine still boot to Windows (grub still not available). I rebooted by live USB then repair with boot-repair. But after that I cannot boot anything, it's only a black screen with 'no operating system' message.

Here is my boot repair report

Boot successfully repaired.

Please write on a paper the following URL:

In case you still experience boot problem, indicate this URL to:
boot.repair@gmail.com or to your favorite support forum.

You can now reboot your computer.
Please do not forget to make your BIOS boot on sda3/EFI/linuxmint/shimx64.efi file!

I'm very new in EFI, help me, thanks!!!
