  • That’s a nice tutorial there Shyam. I’m sure many are going to find it useful 🙂

    • Thanks Anand

  • So what is this – repair, re-install, clean install with user data migration or what?
    I feel confused..

    • Well Repair Install would try to fix any corrupted system files etc. The user data and settings would be intact. Clean Install means you wipe everything out and install a fresh copy.

  • Sorry but this doesn’t erase all my programs installed?

  • Yes correct. Repair Install will not erase all your programs. If you want that the you have to do a Clean Install.

  • thanx great tutorial

  • My computer didn’t come with a separate Windows 7 installation disk. My installation program is on my hard drive behind a partition. In this case, is there any way I can do a repair install without having to buy a new separate Windows 7 Home Premium program? Thanks.

  • Nice Tutorial. My computre didn’t come with a separate Windos 7 disk for reinstallations; my install program is on my hard drive behind a partition. Is thee any way to do a repair install without having to go out a buy a new copy of Windows 7? Thanks.

    • Unfortunately there isn’t. If Windows came with Windows 7 I would recommend contact your Computer manufacturer. On such cases we could only restore the Computer to factory settings. You could always run a SFC SCANNOW. SFC /SCANNOW to Repair Windows 7 Files

      • I ran into the same situation with a Dell PC or no Windows DVD. I borrowed a W7 Pro 64-bit DVD and used my Dell product key code. It did take two tries, the first try hung on the last step or location of your PC, Home, Work or Public. The second try, I disconnected my Ethernet cord and it completed bypassing that last step.

  • Why would you assume I can get into windows if I’m looking to repair install? – Mod Edit – Abusive language is not appreciated.

  • by reparing windwos 7 encryption key will also be deleted ?

  • How do I get a proper chipset driver name without guessing with any driver installation disk

  • I ran sfc/scannow and it scanned 59% and then closed. Is there a way I can run this and have it work. Also, I noticed some S-1-15-2-1 when I check for security is this a virus file?
