A repair on my OS? It's working fine tho.
I did something similar on my previous laptop, from a window XP HD to a laptop running with vista (I took the vista out), it seemed to have no issue, in terms of compatibility and performance.
I'm trying to get a similar model with the similar spec, but worse comes to worst, I might need to settle for something similar (same series, different model of Lenovo).
Even if you have the exact same model laptop, windows may or may not boot. The problem comes from windows product key that is tied with UEFI BIOS to the old laptop motherboard. Most laptops sold 5 years ago comes with UEFI BIOS stored windows product key. (Thats why no windows product key serial sticker anymore). So if you change motherboard, the windows product key is not transferred.
What you could do is, download and run Nirsoft Product key to get the windows product key in your old motherboard. Then the tricky part is to remove the product key in the UEFI BIOS in the new laptop. Even if you did, Windows might still not run if it cannot find the correct product key.
The best way is backup your data and reinstall windows. Else if you bought second hand laptop, just use an external hdd case to read your data.
It is not straight forward as what it was 7 years ago.
