Overwrote my Win 10 OS

[Bonehead_1]

I used the wrong USB recovery drive. I used one for Win 8.1 instead of Win 10, and it is obliterated. Since of I was recovering from a hack when it asked  if I wanted to "remove  ALL partitions". Cool, from scratch,  and no matter what , the OS came with from HP. an I had HP Cloud Recovery as the worse case. Well, not so.

Microsoft store will not let me download The HP Cloud App, because they consider it pirated. Duh, all I want to know is there away without by another OS.

HP matched the serials  and PID's for the system and OS that I bought from the factory. HP sent me to Microsoft for a free tool, but Microsoft wants their product keys to match.

So any suggestions.

Is your PC working but booting into Windows 8.1 instead of Win10?  If so, then you can do the following:

1) Use this information to back off the current HP drivers to a USB stick: https://www.tenforums.com/tutorials/68426-backup-restore-device-drivers-windows-10-a.html

2) Use this link to download and create that media: https://www.microsoft.com/en-us/software-download/windows10

You may see the option to download an ISO file or create media; choose the option to create media. This will take a while because it has to download over 4GB of data and then has to format and create installation media from those files.

Insert that media into your PC, boot from it, and run through the installation. When you get the window asking for a product key, look down near the bottom of the window for the link you can click to skip that step.

When done (the PC will restart several times), you boot into Windows and you get back online, it will contact the MS activation servers and automatically reactivate Win10.

Then, insert the USB stick you used to save the HP drivers and reinstall them all.

• Thanks for the help, I hit a couple of curveballs and have one more hurdle to overcome. The malware uses scheduler to replace anything that is deleted or moved and is then an asset of Trusted installer. 

I am through all of that, but I had to build the OS manually.  Everything went well. It went well, made it to the end. I was very happy. I thought I was done. I left a file out. It was under the assembler window.

Of course, my luck, probably one of the most important files in the entire system the registry key!! 

This is where it stands now. Everything goes great, after login it's black screen. The registry file is still there, how do I get it in

the current state is:

The cloud tool was canabalized to build the OS. 

BIOS is fine.

It just site the waiting for the keys. 

I am open to any suggestions I have the time. My achilles hill is that, I do not have easy access to a second machine.

Thanks all.
