You just can't delete the entire registry in Windows 10. Not while it's running anyway. You may have deleted some keys though.I think you are mistaking it I didn't edited it I deleted it....
I was suspecting that would be the case.I actually tried that but when I try to boot with those it gave me an error that my registry gone corrupt or something and I should repair my computer up by using a windows 10 drive or usb
Make a copy of your registry backup ( the healthy one) and :
After that you can try to import your registry backup and hopefully all will be as it was before the mistake.Download the w10 iso and reinstall. Be sure to set it to keep your files.
If your data folders and files are on the same partition as your OS, you might consider making a Puppy Linux boot [usb or dvd] and copy off your data folders and files onto any trusted external media -- before attempting reconstruction of your Windows.
The only other way that may work, would be trying to do it from a Linux Live DVD to get into the drive. It is a risky move. I have never done it. Also chntpw is a chance. chntpw Freecode

I did not want to go this route, because it can cause more damage if done wrong, instead of doing an in place repair, which keeps everything, but repairs the Windows OS.

No, definitely not. You'd loose everything that way.I didn't get it what do you want to say are you telling me to clean install my system
Here's an idea: copy all your work files and programs from the messed up install to the working install to the exact same locations. I am assuming the working Windows system drive letter is the same as the old one.
After that you copy your registry backup to your working system and we will import that file in your working registry.
Before you proceed make a full image of that working system.

A repair/upgrade install won't work since that system does not even boot.
Hi, you could try this:
Restore your Windows registry
Here is how to restore your registry from the RegBack directory. The RegBack folder is located in :/windows/system32/config, which is used by Windows to hold a recent backup copy of the registry hives.
First, boot from a Win 10 bootable installation medium or other suitable boot disk.
Launch a command prompt.
Carefully identify the drive letter for your system drive (it will probably not be C: )
Assuming your system drive is d:, run the following command to restore Windows registry:
copy d:\windows\system32\config\RegBack\* d:\windows\system32\config
if prompted to overwrite existing files, type All and hit Enter. Type exit and hit Enter to close the Command Prompt window. Restart your computer and most probably, you may able to access your Windows system as before.
Note: we strongly and repeatedly recommend disk imaging (e.g. Macrium Reflect (free).
Using disk imaging routinely lets you recover from anything from a failed hard disk to ransomware usually without technical help, quite quickly.
