After doing a long try, i got success to load Ubuntu 12.04 with Windows 8(dual boot) in my Lenovo ideapad y500. But now window is not working, I simply use legacy mode with UEFI first boot. and whenever i try to install nvidia drivers for linux system, it shows "grub rescue" so i reboot it with live ubuntu 12.04 usb and use this link for boot loader repair

i did it many times with many different ways but still stuck. I did try with linux mint also but with the same problem. Right now i m using ubuntu 12.04 without drivers and windows 8 is not opening.
I am not sure if it boot loader problem or graphics problem. I have seen posts on ubuntu forum related to this but no-one work for me. Please help if someone short out this problem.
