Step 1. Determine what the problem is

Before doing a full reinstall, determine if your problem can be fixed by performing a startup repair. This procedure will replace any operating system files that may have been corrupted. The most common use of startup repair is to repair the Windows loading sequence.

If your computer no longer loads Windows, then a startup repair could fix your boot process and cause Windows to reload again

Step 2. Insert the Windows 7 CD

Make sure your computer is configured to boot from CD. To do this, enter the BIOS immediately after turning on your computer. You will see which key to press below the manufacturer's logo. The most common keys are F2, F10, F12, and Del.

  • In the BIOS menu, navigate to the "Boot" (or "Boot") submenu. Select "CD / DVD" or "Optical Drive" as the first boot device.

Step 1. Create a backup of all important data and files

While this process is safe and there is a very low chance of a critical error, it is always a good idea to back up important data before making any major changes to your system, especially a reinstall. Copy important data to external hard drive, USB stick, or burn to DVD.

Step 2. Gather what you need for the installation

The Windows 7 Product Key is especially important. You can find it attached to the box where the CD came or attached to your computer. Make a list of all the programs that you currently have installed on your computer and that you want to keep so that you can install them after reinstalling the operating system.

Step 4. Begin with the installation

They will ask you to enter some preferences, such as language options, and they will ask you to accept the Windows 7 license terms. You cannot install Windows 7 if you do not accept the license terms.

Step 5. Select the type of installation

After the boot process, you will be offered two options for the type of installation: Upgrade or Custom. Select the "Custom" option as this is the one you need to use to format the hard drive and make it clean for reinstallation.

Step 6. Format the destination drive and install Windows 7 on it

Formatting the drive will erase all data and it will be clean and ready for reinstallation. Although it is not necessary to format, it is recommended to do it when reinstalling the operating system to avoid potential problems with the system. Normally Windows 7 is installed on the C: drive. Windows 7 installation may take 30 to 120 minutes depending on the system.

Step 7. Finish the installation by completing the final details

Once the installation is complete, you will be asked to choose a name for your computer and create an initial user account. Most users leave the default username. After creating the user account, you can use it to log into your Windows 7 operating system that you just reinstalled.

Step 8. Restore the data and programs for which you created the backup

If you had data to save, now is the time to transfer those files back to your computer. If you created a list of the programs you wanted to keep, now is also the time to download and install them

Method 4 of 4: Use the recovery console

Step 1. If you don't want to do a clean install of Windows 7, try the repair tools that come bundled with the operating system

If you press F8 repeatedly during the boot process, you will be able to access the recovery console that comes integrated with the Windows installation.

  • Note: Not all versions of Windows 7 have this feature, but it is a good troubleshooting checkpoint.
  • You can try accessing the command interpreter from the recovery console to fix things on your computer that you couldn't fix through the most common methods. In this case, you will have to repair the MBR (Master Boot Record or Main Boot Record)

Step 2. Access the recovery console by pressing the F8 key during the boot process

Press it repeatedly to ensure that Windows records your keystroke during startup.

Step 3. Press ↵ Enter on "Repair your computer"

Step 4. Click on the "Command Prompt" text that is highlighted in blue

Step 5. Write:

  • bootrec / rebuildbcd
  • Press ↵ Enter.

Step 6. Write:

  • bootrec / fixmbr
  • Press ↵ Enter.

Step 7. Write:

  • bootrec / fixboot
  • Press ↵ Enter.
  • This should be enough to fix any problems with the MBR. Again, this is not included in all versions and variations of Windows 7.
