How to Change an OS Drive

Windows is typically installed on the C: drive. If you've created additional partitions on your hard drive or installed additional hard drives, you may want to move your Windows installation to one of the newer drives. Unfortunately, the risks involved in simply moving your files to the new drive are too great to recommend the process. Instead, you can simply install the operating system on the drive and restore your files, which should prevent any complications.

• 1

  Back up all of your computer files to an external hard drive.

• 2

  Insert the Windows DVD and restart the computer to boot from the disc.

• 3

  Select your language, region and keyboard setup. Accept the license agreement and enter your product key, as requested.

• 4

  Select "Custom" install. Select "Drive Options" when the installation destinations are displayed.

• 5

  Select the new drive you wish to install the OS on. Follow the on-screen instructions to format the drive using the New Technology File System, or NTFS.

• 6

  Repeat Step 5 for the old drive (most likely the C: drive) as well. The will erase your old operating system from the drive, avoiding complications that may come with two versions of the OS installed on two drives.

• 7

  Select the new drive again and click "Next" to install the OS on this new drive.

• 8

  Follow the remaining instructions to complete the install. Once complete, the new drive will be the primary drive and contain the operating system.
