Hi! I have perfectly installed natty 64 bit on my machine alongside with windows.
After a recent windows reinstall as u may guess, the grub was deleted. So i wanted to reinstall it, i know the procedure and i did it before.
The problem is that in oreder to reinstall grub i need to boot into the live CD, but for some reason it doesn't boot, just sticks for a looooong time with ubuntu logo after i choose try ubuntu.

My setup: i5 2500k, Nvdia gForce 460 1G, Gigabyte p8p67 m3 pro, 4Gx2 Gskill DDR3 1600, 1G WD caviar black
