Windows 10: Windows Activation Problem for one of my computers

Hi,


I have a Dell Latitude E7240 which comes with Windows 8.1 Pro. I previously upgraded it to Windows 10 successfully (activated) before the free upgrade. I changed some hardware some time ago and now I try to reinstall Windows 10 and I cannot activate it anymore.


Error code is 0xC004C003.


I got the Windows 8 Pro sticker on the laptop but I can't see the license key printed there. It should have been in BIOS.


I want to activate my laptop now. What can I do? Can somebody work with me?


Thanks in advance.

:)
