So I just installed Ubuntu 12.10 last night. Right away grub gives me the option of Ubuntu and windows 8, when I click on Windows 8, it takes me to the Windows MBR and shows an option for Windows 7 & 8. So pretty much I have to go through to boot menus and I wish to make it so grub handles all three of them. I am new to Ubuntu so sorry ahead of time but how can i fix this?
