Windows 10: windows activation not working after computer repair

Hi, I recently had my motherboard replaced as it was broken. And since then my windows is saying it's not activated. I had an activation code on a sticker on the computer but it is unreadable. I was wondering if there was any way to get my windows activating without having to pay for a whole new code. I tried the troubleshooter and signing into my windows account (that I thought it would be linked to). I installed a backup of my old windows from a usb if that helps.

Repair Windows 7/8/10

Thanks Drone!

Now I'm running into another issue.

I cloned the HDD to Sony Evo 850 SSD using EaseUs todo (the program it came with- Sony Magician didn't work) with success but when I install the new drive it says it's not bootable.

I've searched for this issue on other forums, but many answers pertain to Windows7, or have solutions involving DVD's (I have no blank ones, plenty of USBs however.) I'm hoping I can boot from USB, from what I've read it seems like I can get the proper drivers so it will know how to start up with the new SSD. If anyone knows how to do this, I would need step by step instructions.

As a newbie to DIY computer repairs, I am feeling stumped at this point! I feel so close yet so far..

Specs for my ultrabook: Acer m5 581t
New SSD: 250gb sony evo 850

Any hints or suggestions welcomed!

Thanks!
