How to Dual Boot Windows on the Computer

When dual booting a computer, it would be better to install the different systems in two separate partitions. If you don't have an external hard drive, you can create a partition on your computer for Windows installation. Here we will introduce how to create a partition on the hard disk first, then show you how to install Windows 10 on the newly created partition.

Part 1. Create a Partition for Windows 10 installation

The easiest and safest way to dual boot is to buy and install a new hard drive for the new operating system on a computer. But if you have a large enough hard disk, you can also repartition the hard disk to make space for the new Windows installation.
