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?
