That’s it, you’ve completed the repair install!
Make sure that you should be performing a repair install.
This process is not always the one-stop fix all for all non-boot situations. Follow the procedure below only if you can still boot into Windows.
1.Manually delete the Undo_guimode.txt file from the Windows\System32 folder. This should be done before you continue through the symptoms section above.
2. Delete this by opening the command prompt. Click on start and choose Run.
3. In the run box type cmd and click OK.
4. Type this in the Command Prompt window: del /a /f c:window\system32\undo_guimode.txt and press Enter. (See photo below)
What should I do if the repair option is not available?
**If the repair option is not available and you continue with the process you will delete your Windows folder, Documents and Settings folder, and all software that has been installed will need to be reinstalled. **
You should exit the setup process if the repair option is not available for you to choose and look for another option. These options may be to purchase a new hard drive and perform a clean install on that and then restore your media to it. You are able to get important documents and files from your old hard drive and move them to the new one.
Before connecting to the internet, make sure to apply updates and reinstall service packs. If your installation media did not have the service packs originally, then a repair install will remove them and you’ll need to add them to your installation media with the process below.
The best way to do this is to create a SlipStreamed Installation disk. This process will put the Service Packs on your original installation DVD.
