How To Have Windows 7 And 10 On Same Computer

Do you want to have both Windows 7 and Windows 10 installed on your computer, but you’re unsure of how to achieve this? You’ve come to the right place! In this blog post, we’ll walk you through the process of setting up a dual boot system, allowing you to have both operating systems on your machine.

Why Install Both Windows 7 and Windows 10?

There are several reasons why you might want to have both Windows 7 and Windows 10 on your computer:

  • Some older software may not be fully compatible with Windows 10, but still work perfectly in Windows 7.
  • You might be more familiar and comfortable using Windows 7, but still want to have access to the latest features and updates available in Windows 10.
  • Testing software or websites for compatibility with both operating systems.

Before You Begin

Before you start setting up a dual boot system, make sure you have the following:

  1. A valid Windows 7 and Windows 10 license key.
  2. A computer with enough hard drive space to accommodate both operating systems (at least 50GB for each).
  3. A backup of your important data, as there is always a risk of data loss when working with partitions and operating systems.

Setting Up a Dual Boot System

Follow these steps to set up a dual boot system with Windows 7 and Windows 10:

Step 1: Create a Bootable Windows 10 Installation Media

  1. Download the Windows 10 Media Creation Tool from Microsoft’s website.
  2. Run the tool and select Create installation media (USB flash drive, DVD, or ISO file) for another PC.
  3. Choose the language, edition, and architecture (32-bit or 64-bit) for Windows 10.
  4. Select the media type you want to create (USB flash drive or ISO file).
  5. Follow the on-screen instructions to complete the process.

Step 2: Create a New Partition for Windows 10

Before installing Windows 10, you’ll need to create a new partition on your hard drive for the new operating system.

  1. Open the Disk Management tool in Windows 7 by right-clicking on the Computer icon on the desktop, selecting Manage, and then clicking on Disk Management under Storage.
  2. Find the primary partition where Windows 7 is installed (usually the C: drive). Right-click it and select Shrink Volume.
  3. Enter the amount of space you want to allocate to the new partition (at least 50GB) and click Shrink.
  4. Right-click the unallocated space and select New Simple Volume. Follow the wizard to create a new partition.

Step 3: Install Windows 10

  1. Insert the bootable Windows 10 installation media (USB flash drive or DVD) that you created earlier.
  2. Restart your computer and boot from the installation media.
  3. Follow the on-screen instructions to install Windows 10. When asked where to install the operating system, select the partition you created in Step 2.
  4. Finish the installation process and set up your new Windows 10 system.

Step 4: Configure the Dual Boot

After installing Windows 10, your computer should automatically set up a dual boot configuration. When you start your computer, you’ll be presented with a menu to choose between Windows 7 and Windows 10. To change the default operating system or the time delay before the default OS starts, follow these steps:

  1. Boot into Windows 10.
  2. Right-click the Start button and select System.
  3. Click Advanced system settings.
  4. Under the Startup and Recovery section, click Settings.
  5. Use the dropdown menus to adjust the default operating system and time delay.
  6. Click OK to save your changes.


Now you have successfully set up a dual boot system with Windows 7 and Windows 10 on the same computer. You can easily switch between the two operating systems whenever you want, giving you the best of both worlds. Enjoy!
