How can I run update-grub if I can't boot into linux?
I downloaded Ubuntu 64bit and installed it from a CD. Everything went fine the partitions were correct but when I start my computer there is no option for I have a system of 8GB Ram, GTX 670 and i5 3570. I also have a durable mothereboard. I want to choose between the Ubuntu and Windows before booting. I know that the bios can help and maybe you have to tell it where to search to boot. But I don't know of this stuff and I want details how to do it.
