Insert the Windows installation media into your Lenovo ThinkPad and restart the computer.
Press the F12 key repeatedly to enter the boot menu. Select the Windows installation media and press Enter.
Follow the on-screen instructions to install Windows. When you reach the "Where do you want to install Windows?" screen, select the partition that contains the current Windows installation and click "Delete." This will erase all data on the partition.
