I earlier had Windows 7 installed on my laptop...then installed Windows 8 with dual boot setup on a different partition.

Then I didnt like windows 8 so much and decided it to replace with ubuntu 12.04. So I booted into Live CD and formatted my Windows 8 partition to ext4. Set mountpoint as /. and installed Ubuntu succesfully.

Then when I booted the computer. It detects the Windows 8 system and not Windows 7 which is actually present on my lappy.

When i click on Windows 8 entry in Grub2. It takes me to Windows 8 repairing stuff. How can i get my system to dual boot Windows 7 and Ubuntu?

Well, this is not Grub2 problem. It is related to BCD configuration. Actually, Windows 8 replaces every bootloader without confirmation like any Windows does. And Microsoft apparently had chosen wrong way last time, because their so called "boot screen" is not actually boot screen but logon screen. When you deleted Windows 8 partition, you made Windows system totally unbootable. Now you should perform these steps to correct the problem:

  1. Choose Windows 8 in GRUB2 menu.
  2. Find entry "Run earlier version of Windows" and select it. (May be you need to hold F8, not sure).
  3. Reboot.
  4. Repeat step 1.
  5. Boot into Windows 7.
  6. Run EasyBCD. There, you should do:
    • Rewrite Windows bootloader.
    • Set up Windows 7 boot entry and set it to default.
  7. Reboot into Ubuntu and update GRUB menu.
  8. Check if Windows 7 starts normally.

And you always can restore Windows 7 bootloader using it's installation media, then restore GRUB again.
