Points to note before a dual boot

You must have a bootable device. Create one using an .iso of the required operating system with a boot device creator like Universal USB Installer or Rufus.
If your disk type is MBR, look into how to create more than 4 partitions using extended partition as only 4 primary partitions are allowed by it with a max space of 2 TB.(I’d suggest converting it to GPT but dont forget to make a backup as this process erases all the data on that disk, NOTE: on the whole disk not just that partition)
Try and have both the OS installed in the same mode, i.e. Legacy or UEFI. Windows Supports UFEI.
Boot with secure mode off in your BIOS setup.(Be very cautious when you enter your BIOS setup and reme’mber the changed you make in case you need to revert back if something goes wrong)
Let the OS install additional drivers if you are new to this, otherwise you might find a few drivers like WiFi drivers missing.
Always create a grub partition (in case of Linux-based OS) so that you can switch between your OS.
