So, let's remove Grub first, it ****ed up your whole installation. Download and burn the Ultimate Boot CD and boot it. Select HDD, Boot Management, Super GRUB disk. Type: The sh*tload of ('s aren't mine idea...

Now you've only got Windows. Feels good, huh? No, it shouldn't. We're goin' to install GRUB again.

Start from a Live CD and start the terminal. From there, mount the partition Ubuntu is installed on. You don't know? sudo fdisk -l. . Now reboot (sudo shutdown -r now) and remove the cd. Ubuntu will start from the HDD. In the terminal: . If it ****s your Windows up again, you should try Ubuntu 12.10, I think it has a newer Win8 compatible GRUB.


EDIT: You shouldn't use Windows 8 btw, I know you're a child, but Metro is a playground for 4 year olds... Even I (14 years) think that, so...
