How to reinstall Windows 10 in your Dell Inspiron PC

Unless you have one of the latest Dell machines, you most probably simply upgraded older operating system version with Windows 10. While this is fine for majority of users, upgrading can be detrimental to the system in the long run because unnecessary bugs, files, and rubbish will be carried along. As much as possible, you want to do a clean install in order to minimize bugs from developing. If you are not familiar with how to perform a clean operating system install, here’s how:

  1. Create a backup of your irreplaceable files. This should be the very first step in this guide. You don’t want to lose important data. To give you an idea on how to start, kindly follow this previously published article.
  2. Prepare the installation media. The next thing that you want to do is to ensure that you have a bootable media to proceed with the installation. The most convenient media that you can use of course is a USB flash drive. Based in our own experience, it’s good if you can use an 8GB flash drive. It should give more than enough storage space for the installation package. For more details on how to prepare the installation media or drive, follow this link.
  3. In your computer, click on the Start button.
  4. Click on Settings.
  5. Click on Update & Security.
  6. Click on Recovery.
  7. Click on Get started when you are in Reset this PC page.
  8. Follow the prompts on screen. If you are installing Windows to a new drive, it will be indicated as a blank drive so make sure to choose the large unallocated space. During installation, your Dell Inspiron laptop may reboot on its own. This is normal. If you are using a DVD or flash drive, make sure to keep an eye on the screen from time to time as the machine may ask you to remove drives.

Another simple way to begin Windows reinstall right away is by inserting the bootable installation media in your PC and restarting it. As long as your PC has been set to boot from your flash drive ahead of time, the installation wizard that pops up should walk you through on what you need to do. Again, make sure to back your files up before doing a reinstall this way.

Make sure to activate Windows after the reinstall

Once you’ve finished the installation, don’t forget to activate Windows by doing the following steps:

  1. Go back to Home screen.
  2. Right-click on the Start button.
  3. Click on System.
  4. Check if Windows activation section indicates that your OS version has been activated. Normally, Windows will be activated automatically once you connect to the internet (assuming of course that you have a previously activated Windows version). Activation may take a few minutes so be patient and wait for the confirmation in the Windows activation section.
