I have two options for Windows 7 in GRUB but one is broken and just says "CTRL-ALT-DEL to restart." the other Windows 7 option works just fine. Here is the error message that grub customizer is giving me

grub-mkconfig couldn't be executed successfully. error message: Generating grub.cfg ... Found linux image: /boot/vmlinuz-3.0.0-16-generic Found initrd image: /boot/initrd.img-3.0.0-16-generic Found linux image: /boot/vmlinuz-3.0.0-12-generic Found initrd image: /boot/initrd.img-3.0.0-12-generic Adding Windows Adding Windows /etc/grub.d/11_Windows.save: 9: ^K: not found

As root, edit the file /etc/default/grub, remove the bad entry, something like:

menuentry 'Windows 7'

Then sudo update-grub.
