How can I repair grub? (How to get Ubuntu back after installing Windows?)

In Live CD I went in the terminal and when I do sudo update-grub it responds

/usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?)

Here's the breakdown of my drive:

sda1 - vfat - Windows 7: FAT32
sda2 - 
sda3 - nfs - Windows Vista/7: NTFS - Windows 7
sda3/Wubi: - 
sda4 - Grub2
sda5 - Ubuntu 12.04.1 LTS
sda6 - 
sda7 - 
sda8 - BIOS Boot Partition

Also at the top of the page it states : 

=> No boot loader is installed in the MBR of /dev/sda

Any and all help is appreciated and welcomed.

When my computer boots, it goes into GRUB and has the options for Windows 7 and Windows Memory Test but no option for Ubuntu. I want to run a dual-boot through it.

    Hm..., what do you mean by "sda4 - Grub2"? What's Grub2 doing on a separate partition? Any particular reason it's there? Is it really there? By the way, this is the way to reinstall GRUB. Do not hesitate to ask if you need help with that. – mikewhatever Oct 18 '12 at 01:18

In order to repair grub from the LiveCD you need to chroot into the filesystem on the hard drive, otherwise it will try to repair the filesystem on the CD - hence the errors.
