  1. Open the Windows 10 Start screen and type “cmd” into the search bar.

  3. The Windows 10 partitioning window will open and you will be able to select one of your hard drives or SSDs as your primary partition. You can also add additional partitions if you have them available. If you don’t have any hard drives or SSDs, please select “None” in the window’s “Format options” section to continue with the default settings.
  4. In the “Partition options” section, you can choose to use a GUID (GUID Partition Table) for your new partition or use an NTFS (New Technology File System) file system for your new partition. If you choose to use a GUID for your new partition, make sure that it is at least 8 characters long and has at least one letter followed by a number (e.g., C:\Users\username\AppData\Local\Temp). If you choose to use an NTFS file system for your new partition, make sure that it is at least 4GB in size and has at least 50% free space on each disk (i.e., C:\Users\username\AppData\Local\Temp\00050000). Please note that using a GUID for your new partition does not guarantee that it will be created successfully; if it fails, please try again later with another drive or disk combination!
