I first need to format the disk.

How is this done ?

You don't need to partition and format the disk. Windows will do this automatically on a clean install. The below guide is for Windows 8.1 but the steps are the same for 7 or 10. Delete all partitions unless you have a separate data partition on the drive. After deleting partitions install Windows to the unallocated space. Windows will automatically partition and format the drive. On Windows 10 or 8 it's not necessary to provide a key as on an upgrade to 10 the license is stored on Microsoft servers and any computer pre-installed with 8.1 or 10 has the key embedded in firmware.
