Do i need to buy windows again?

Hello guys so today i just changed my laptop's hard disk and the person who change my hard disk says that i need to buy windows again in order to receive windows 10 which im wondering if its true or not because i have an original windows before, so now i leave my laptop without os because im so confused, really need a help. thanks!

What OS did your laptop have on it before you changed your hard drive? If it ever had Windows 10 on it, then you are good to go and you do not need to buy another copy of Windows 10, the guy was wrong.

yes my previous os was windows 10 thank you, do you know how to install win 10 without os in a laptop? i dont have a disc, i buy it with a serial key

Your first clue that this guy was all wrong is that, if you have a valid purchased serial, this allows install on one PC at any time !

If there is no OS now, Go to this Microsoft page - Windows 10 and follow Looking to install Windows 10 on your PC? (have your serial on hand)

If there is an OS; 7, 8, 8.1 use the top of the page where it says Update now and run download from desktop by mounting via r-click and hitting setup.

Use the Media Creation Tool on an operating computer to make a Windows 10 USB installation flash drive or DVD. It's the Download tool button here:

Windows 10

Then you boot the laptop from the Windows 10 USB flash drive or DVD the media creation tool created and install Windows 10 from it. Just make sure you select the matching version/edition of Windows 10 your product key is for. You can verify that by running it through the "check product key" function of showkey plus:
