Reinstalling Windows 7 every 6 to 12 months, instead of never doing it at all, can keep your computer running as smoothly as possible. For those who are not very computer or technology savvy, reinstalling an operating system like Windows 7 can seem daunting. Fortunately, this process is simpler than older versions of Windows, with very little risk of failure. Keep reading to learn an easy way to repair or reinstall Windows 7.

Step

Method 1 of 4: Performing a Startup Repair

Step 1. Determine what the problem is

Before performing a complete reinstallation, check if your problem can be fixed by performing a Startup Repair. This will replace your operating system files that may have been corrupted. The most common use of startup repair is to repair the loading order of Windows.

If your computer no longer loads Windows, then a startup repair can repair your boot process and allow Windows to load again

Step 2. Insert the Windows 7 CD

Make sure your computer is set to boot from the CD. To do this, enter the BIOS as soon as your computer starts up. You will see a button to press under the manufacturer's logo. The most common keys are F2, F10, F12, and Del.

• In the BIOS menu, navigate to the Boot submenu. Select CD/DVD or Optical Drive as the first boot device (1st boot device).

  

• Save your changes and exit the menu. Your computer will restart automatically.

  

Step 3. Enter Windows Setup

Press a key when the message “Press any key to boot from CD or DVD…” appears on the screen. This will take you to the Windows setup. The files will load for a while, then a screen will appear asking you for your Language and Time preferences. It should have been filled in correctly. Click Next to continue.

Step 4. Click Repair your computer

It's in the lower-left side of the screen below a large "Install now" button. You will be taken to System Recovery Options after clicking "Repair your computer".

• The program may take a while to locate your Windows installation. Select your installation from the list and click Next. For most users, there is only one installation on the list.

  

Step 5. Select Startup Repair

The Startup Repair tool will start searching through your Windows files, looking for errors. Depending on the errors found, the tool can suggest solutions or fix them automatically.

• Unplug all flash drives or external hard drives, or Startup Repair will not work properly.

  

• Your computer may reboot several times. Do not boot from the CD when this happens, or you will have to start the process again.

  

Step 6. Click the finish button

After the repair is complete, click the Finish button to start Windows normally. If Startup Repair does not detect any errors, this screen will not appear.

Method 2 of 4: Performing a System Restore

Step 1. Run the System Restore tool

Depending on whether or not your Windows boots, you have two different ways to run System Restore.

• If the computer cannot load Windows, follow steps 2-4 in the previous section to enter System Recovery Options. From there, select System Restore.

  

• If you can log into Windows, click the Start button. Select All Programs, then Accessories. Select System Tools then click the System Restore icon.

  

Step 2. Select a restore point

You can choose from restore points that you create, restore points that are scheduled automatically, and restore points that are created when installing certain programs and updating Windows. You can only restore your computer to the date listed here.

Step 3. Click Next, then Finish

Click Yes for final confirmation. Your system will start the recovery process. Your computer will restart automatically during this process. Recovery can take a few minutes. When you log into Windows after completing the restore, you will see a message saying that the process was completed successfully.

• System restore will not restore deleted files.

  

Method 3 of 4: Performing a Clean Install

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

While this process is safe and there is little chance of a critical error occurring, we recommend that you back up any important data before making any major changes to your system, especially during a reinstallation. Copy important data to an external hard drive, external flash drive, or burn that data to a DVD.

Step 2. Gather what you will need to perform the installation

Your Windows 7 product key is very important. These can be found tacked on to the included CD case or pasted on your computer. Make a list of all the programs currently installed on your computer that you want to keep so that you will be able to install them again after reinstallation.

Step 3. Run the Windows 7 installation

Insert the disc into the computer and reboot your computer. Make sure that your computer is set to boot from the CD/DVD. You can do this by following Step 2 of the first part of this guide.

Step 4. Start the installation

You will be asked to enter some preferences, such as a language choice, and you will be asked to agree to the Windows 7 license terms. You cannot install Windows 7 if you do not accept the license agreement.

Step 5. Select the type of installation

After the boot process, you are given a choice: installation Upgrades or Custom. Choose the Custom installation option as this is what you will be using to clean your hard drive to perform the reinstallation.

Step 6. Format the destination drive and install Windows 7 there

Formatting the drive will thoroughly wipe all data and make it suitable for reinstallation. Although this format is not necessary, it is recommended when reinstalling to prevent potential problems with the system from occurring. Usually, Windows 7 will be mounted on the C: drive. Installing Windows 7 can take anywhere from 30 minutes to 120 minutes, depending on your system.

Step 7. Complete the installation by filling in the last details

Once the installation is complete, you will be asked to name your computer and create an initial user account. For most users, the default name will suffice. After creating your user account, you can use it to log in to your newly installed Windows 7 operating system.

Step 8. Restore the data and programs you saved backup

If you have any files that you backed up, now is the time to move them back to your computer. If you've made a list of programs you want to keep, this is also a good time to download and install those programs.

Method 4 of 4: Using the Recovery Console

Step 1. Try creating a repair tool with your operating system if you don't want to do a clean install of Windows 7

Pressing the F8 key repeatedly during the boot-up process allows you to access the Recovery Console which is included in the Windows Installation.

• Note: Not all versions of Windows 7 have this feature. However, it's a good idea to check when you have problems.
• You can also try accessing the command prompt from the recovery console to solve problems on your PC that cannot be fixed by normal methods. In this case, what will be fixed is MBR (Master Boot Record).

Step 2. Press the F8 key during the boot up process to access the Recovery Console

Press this key repeatedly to make sure it is registered to Windows during the boot process.

Step 3. Press Enter on Repair Your Computer.

Step 4. Click text Command Prompt highlighted in blue.

Step 5. Type:

• bootrec /rebuildbcd
• Press Enter.

Step 6. Type:

• bootrec /fixmbr
• Press Enter.

Step 7. Type:

• bootrec /fixboot
• Press Enter.
• This method should be successful in overcoming MBR Problems that may arise. However, again, not all versions and variations of Windows 7 have this feature.
