I have recently installed windows 7 ultimate through bootable pen drive in drive E. It would be important to inform you that windows 7 Home Basic was already installed in my computer in drive C. Now there was no need of windows 7 Home Basic so i deleted that partition. Now when I restart my computer it shows two Operating Systems i.e windows 7 Ultimate and windows 7 Home Basic. Windows 7 Ultimate works fine but when I click on windows 7 Home Basic, it ask me to either perform a repair or install a windows 7. First of all I tried to solve this issue but it was difficult to solve so I formatted both of these partition and installed a fresh copy of windows 7 from DVD. Everything is working fine but it still shows the same message at boot screen. Is there any way to solve this issue?
