Windows 10: Getting my Windows license back after re-installation even though I didn't register it on...

Hi, so I've just upgraded my old laptop (running Windows 7) from using HDD to SSD. After cloning the data from the internal HDD to SSD, I swapped them and loaded the Windows using the SSD and then updated it to Windows 10. It worked just fine but then I had an issue with the laptop's battery that can't be detected and I tried changing the battery but it didn't work. I could only use my laptop while the AC adapter is plugged in. Because of that I just wanted to use the SSD as an external hard drive for other purposes and put the HDD back inside the laptop. I cloned the data from the SSD to HDD and swapped them again. The thing is now I can't load the windows from the HDD, it says bootmgr is missing. I tried repairing the Windows with the bootable flash drive but none of the repairing options worked. All I assume I can do is clean installing the Windows 10 again. But the thing is I haven't registered the Windows license with my Microsoft account so I am not sure if I can get the license back if I try to reinstall the windows. And unfortunately I have formatted my SSD already so I can't reload the windows using it and register it first.


So.... is there a way for me to get the license back after I re-install the Windows?

why won't windows launch after install new MB and CPU?

To repair windows properly-

• Boot into install CD for XP (if you don't have one, go buy it. For the repair to work, it has to coincide with the version of XP you have).
• Act as if you're going to install Windows, press "install windows", agree to license.
• Wait for it to detect all previous installations of Windows. It will then ask if you would like to repair any of them.
• Select the partition you want to repair, and then go play firsbee...or whatever you do for fun.
