I want to install Windows7 on my system with pre-installed Ubuntu 11.10 to play some games in my relax time.
But after installing Windows7 over Ubuntu my computer doesn't show OS chooser (GRUB) in the beginning of system startup.
Now I've lost my Ubuntu installation disk but I still have its .iso file. I can't, or don't want, to burn it to a CD/DVD?
Is there any way that I can use that .iso image to repair system startup without need to burn that CD again?

Its easy to install duel OS but If you install windows after Ubuntu Grub will be affected. Grub is a booting system of Linux base system. You can follow above steps or you can do just the following....
To fix booting problem you can install a program 'EasyBCD' in Windows. Download it here
Follow these steps to restore GRUB when after installing EasyBCD:
GRUB will be displayed after the restart which will detect the Ubuntu partition for you to be able to boot into Ubuntu
