Creating Windows Installation Media on ChromeOS

Let's discover how to create a Windows Installation Media USB using CMOS on a ChromeOS device such as a Chromebook.

What you'll need

• An 8GB or larger USB stick/flash drive
  • If you need one, we recommend and test with the following USB stick
    • Samsung BAR Plus 64GB
• CMOS
• Windows Disk Image

Creating the Installation Media

On your ChromeOS device

1. Format your USB stick/flash drive
   1. Use the Files Application that comes preinstalled with ChromeOS.
   2. Right-click the USB stick/flash drive and select Format device.
   3. Leave the Drive name blank and set the Format to FAT32
   4. Click Erase and Format
2. Copy the Zip contents from within CMOS to the root directory of your USB stick/flash drive.
3. Split the contents of the Windows Disk Image with the File Splitter, and save them to the root directory of your USB stick/flash drive.
   1. Tip: You can change your default save location in Chrome to be the root directory of your USB stick/flash drive.
      1. Navigate to chrome://settings/downloads within Chrome to access these Downloads settings.
4. Double check you created your USB properly

   1. Note: Duplicate files (files with (x), ie. (1) in filename) will break the process!

   2. The following is a directory listing of a proper and valid USB. Use this as a reference.
