Cannot boot PC after resetting WIndows 10

Hi

I upgraded my Windows 7 Home Basic to Windows 10 yesterday. It was successfully activated. I loved the UI and animation.

But I could not sign into my Microsoft account, hence could not use Cortana or sign into store. I got "Something went wrong" error all the time. Multiple reboots did not solve the issue.

I decided to reset my PC completely and proceeded without keeping anything though it warned me "This might take several hours". My PC got stuck at 99% for like 4-6 hours. I kept it at that stage the whole night.

When I woke up this morning and saw, my PC had a blue screen error saying "We will restart your PC bla bla INACCESSIBLE_BOOT_DEVICE". This error is existing after multiple reboots also.

The two options I can think off:

1. Rebuild my Windows 7 all over again and upgrade to Windows 10 (I am afraid it may not solve the problem).
2. Do a clean install of Windows 10.

I don't want to do the first.
Is there anyway I can claim the same license that I already have for Windows 7 in second scenario? I don't mind losing the existing Windows 7 license if I get one for Windows 10.

If you've successfully upgraded you can clean install 10. You'll even be able to revert back to 7 if you so desire.

Thanks cyberrufus. But I did not retain any trace of Windows 7 or any of my personal files. My intention is to get a fresh Windows 10.

What I meant was that if you have the 7 install media you can still go back to it. If you want to clean install 10 do it. Just make sure if asked for any keys during the install you skip that step.

Okay, If I install Windows 7 Home Basic (it will get automatically activated) and install Windows 10 Home over it using ISO, will I have an activated Windows 10 on my device for lifetime?

It appears you previously successfully upgraded so you should be able to clean install without any problem. No need to play around with 7. Yes, the activation will be for the lifetime of your device.

Will give it a try and update, thanks :)

Did a clean install of Windows 10. Initially it asked me for product key and I just skipped it. Once the installation is complete, I see my Windows 10 activated :)

However, I wonder how there is Backup and restore (Windows 7) option in control panel though I did a clean install.
Is it like when I want to go back to Windows 7, it will retrieve the data from the cloud and restore?

That's from a clean install of 10 over 8.1 and I've never had 7 on this machine. That's just how the CP is and it's meaningless.
