If you’re looking to mirror your Windows 7 desktop to your Roku streaming device, there are a few things you’ll need to do first. Here’s how to get started:

  1. Download the Windows 7 Media Creation Tool from Microsoft.
  2. Run the tool and select the Windows 7 installation you want to mirror.
  3. Click on the “Create a DVD or USB Drive” button and choose “Create a DVD.”
  4. Insert your blank DVD into your computer and click on the “Start” button.
  5. When the Windows 7 installation begins, click on the “Repair Your Computer” option and then click on the “Advanced Options” button.
  6. Click on the “Startup Settings” tab and select “Enable booting from CD/DVD.”
  7. Click on the “Browse” button next to where it says “/dev/sr0”. This will open up a list of devices in your computer, including your DVD drive (if it exists).
  8. Change the value of “/dev/sr0” to point to your Roku streaming device’s optical drive (if it exists). You can find this information by going into your Roku’s settings and looking for its device name (it should start with “/dev/”). For example, if my Roku’s device name was “/dev/rdisk2”, I would change sr0’s value to “/dev/rdisk2”.
  9. Click on OK when you’re done setting up your mirroring options and restart your computer when prompted by Windows 7. Now you’re ready to start mirroring! ..
