SOLVED Windows 10 activation issues

[salilsurendran]

Hello,
I bought a new laptop with Windows 7 Pro on it and it was upgradable to Windows 10. However, the upgrade failed. Also my new laptop had a HDD so I replaced it with my old SSD. I installed Windows 10 from USB doing a clean install. However, it doesn't activate. I entered a Windows 7 Home Premium Key that I had from my previous laptop but that doesn't get activated and I get a 0xC004F050 error. How can I obtain the Windows 7 Pro key necessary to activate from the old HDD lying outside of any computer? Do I have to put it back into my laptop?

Is there a COA sticker on the laptop anywhere? Have you checked the battery compartment, sometimes their under the battery?

the upgrade failed

Any further information as to why "the upgrade failed"
Did you download the ISO and attempt the in-place upgrade from a local resource, rather than over the wire?

The installation media can be obtained through either of these two resources.

https://www.microsoft.com/en-us/software-download/techbench
OR
http://www.microsoft.com/en-us/software-download/windows10

Once you have the ISO, you can use ImgBurn to burn it to a DVD or Rufus to burn it to a USB ThumbDrive, either of which you can use to perform the in-place upgrade by simply clicking the setup.exe application on the media from within your running version of Windows.

I checked everywhere there is no COA. All my old Windows 7 original disks are on CDs/DVDs. My new laptop has no optical drive. So I can't easily install the older version on my new machine and then upgrade to Windows 10

I called Lenovo support and they extracted the key from my motherboard and I upgraded my Windows 10 to Build 10586. The key extracted from my motherboard worked and Windows 10 got activated.
