No Grub and Can't Boot into Windows 8 After installing Ubuntu 12.10
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
First, I installed Windows 8 in my desktop PC. (Not pre-installed... I did it by myself). Then I booted the Ubuntu dvd in UEFI mode (Did the same with Windows 8) and installed Ubuntu 12.10 64bit. Everything went perfectly. After rebooting, there's no grub! The system took me directly to Ubuntu! I can't log into Windows 8. Please help! Earlier, I used Boot Repair and it messd up with my Windows EFI files. So I was unable to boot Windows even after removing Ubuntu. I can't use boot repair. Now this is a new fresh install, Please tell me how to boot into both Windows 8 and Ubuntu!
Here is my /etc/defaults/grub :

@penreturn Thanks! It brought back grub. But can't boot to Windows 8. I added it by following this guide askubuntu.com/questions/210914/… . Now grub gives an error when selecting windows 8 : error: file '/EFI/microsoft/BOOT/bootmgfw.efi' not found. But when checking, through Ubuntu, i can find that file

Run Boot-Repair --> Advanced Options --> tick Restore EFI backups --> Apply , and indicate the new URL that will appear. Reboot, you should get back access to Windows.

I recently installed Windows 8 Pro to an extra hard drive on my PC. My system which runs Ubuntu primarily and boots up through GRUB couldn't seem to find the new OS after I installed it. So I searched and read all of these solutions involving manually re-configuring GRUB system files, uninstalling and re-installing Windows, etc. All of these are terrible solutions. The best solution is so, so easy. All you have to do is run this update command for GRUB from a terminal window within your Linux distro:
$ sudo update-grub
It searches your hard drives for new kernels and OSs. Problem Solved. Enjoy!
