I have installed ubuntu 12.10 from cd from then i can't boot windows 7. My system is directly booting into ubuntu linux. During installation, i didn't get any option to select ubuntu along with windows.
Ubuntu writes over the Windows bootloader with it's own called GRUB. There needs to be an entry in here for Windows. Sounds like this has been missed out.
Open a program called GParted. It comes pre-installed with Ubuntu.
You should be able to view all hard drives and partitions available. Make sure your Windows partition is still present and note which disk/partiton number it is on. For example it could be hd0,1
Next can you open a terminal and type this:
su cat /boot/grub/grub.conf
Post back the output please.
