If you're looking to rebuild, restore, or simply troubleshoot your laptop, it can be very helpful to understand how to boot your computer into a Recovery Partition. By default, many computer manufacturers often divide hard drives into two partitions, whereby drive C is dedicated to the main operating system, with the computer's D drive serving as a second, smaller hard drive.
This tutorial will teach you how to access the recovery partition of your Windows laptop (specifically Asus). Note that this procedure can also be used if your recovery discs are damaged.
