I have dual Ubuntu 12.04 and Windows 7 installed in my PC. I installed Ubuntu after Windows, and I have issues with GRUB. After installing Ubuntu, there was no boot loader in the start up, with an error message about missing OS. I tried boot repair, I can see the GRUB loader now and can access Ubuntu, uut I am not able to access Windows, even though I can see that in GRUB loader.

I tried to fix the Windows start up with my Windows Live CD, but that removed the GRUB.

What should I do in this case?

This worked for me in a similar situation. At the next boot, I held Shift until I got "Missing operating system". Rebooted again, and GRUB showed the list of options, including Ubuntu and Windows 7.
