Black Screen After Malware Removal. Help!

[gopanda]

Hello!

I used Malwarebytes to remove malware, browser adware and some SNARE virus

After Scan There was about 3000 detected files. So I was a bit paranoid and I think I deleted them immediately from quarantine and restarted.

Now I have Black Screen after windows logo loading, no cursor nothing.

I can access Safe Mode option menu but Safe Mode also have Black Screen.

I did 2 System Recovery points but it didn't work.,

I booted my PC using windows 8,1 installation USB and tried to REPAIR, didn't work.

I tried to upgrade to windows 10 using USB to fix it but it does not allow me to do that without access to my current windows.

I didn't tried REFRESH, RESET and CLEAR INSTALL yet because I don't want loose very important files.

Possible Causes

1. Important system files was deleted when removing malware

2. My SSD was full, was in very low memory and I also did AVG update right before restart

3. Virus is blocking access.

How can I fix it without loosing my files and apps?

Are There any bootable USB software that can Help?

Please can you give me any advice?

I have an idea to buy new HDD and install windows there and after open my SSD as second to recover files from it. Is it possible? 

Also my PC goes to Sleep mode when running in Black Screen after about a bit less then 1 hour.

Update. I am able to access my computer using cmd.exe /notepad. All Drives looks good. 

But I noticed that my SSD where windows is installed is no set as Primary C: It is set as last G: not as usually it was.

Is it possible that problem is only because windows is booting from wrong Drive?

How can I change it to back to C:?
