Some countries like India only includes FreeDOS and not Windows 10 (or other versions) to keep the price low. That means when you boot the laptop you will see the C:\> (called C prompt) staring back at you.
As mentioned above, you will need to install Windows in order to actually use the laptop. Be aware that 7th and 8th generation Intel CPUs will only allow Windows 10 to install and operate properly. Microsoft made a deal with Intel (and AMD) to only allow Windows 10 (and most likely future Windows versions) to be installed on current generation CPUs.
