Copying a Windows installation CD to a USB drive is a good idea in case the CD or DVD drive ceases to function. Unfortunately, the process isn't as simple as copying the files from the CD to the USB drive in Windows Explorer. Specialized software is required to ensure that the Windows CD is correctly transferred to the USB drive. WinToFlash is a free application that makes an exact and bootable replica of a Windows installation CD on a USB drive (see Resources).

Download WinToFlash. Extract the .zip file. Double-click "WinToFlash.exe" to launch the application.

Click the green check mark, and then click the "Next" button.

Place the Windows installation CD into the disc drive. Click the "Select" button on the "Windows file path" line. Choose the disc drive containing the Windows installation CD from the list.

Connect the USB drive to the computer. Click "Select" on the "USB drive" line. Select the USB drive from the drive list. Click "Next" to proceed.

Click the "Continue" button when the licensing agreement appears.

Click "OK" at the warning prompt. WinToFlash will now format the USB drive and copy the Windows installation CD to it. Quit WinToFlash when the process is complete.
