Hi, -I have installed Windows 7 on C:\ which is primary. -I installed windows 7 again on G:\ -Then I did format of local disk G:\. But while booting, it still showing two Windows 7 OS options to select. And if I select 1st one it asks for system repair. So, please tell me how can I completely uninstall the OS installed on G:\? Thanks.
As you have already formatted the partition, data related to the previous os is gone. You just have to remove the old boot entry.
