Hi,
The BAD_SYSTEM_CONFIG_INFO bug check occurs if the SYSTEM hive is corrupt. However, this corruption is unlikely, because the boot loader, known as NT Loader (NTLDR) in versions of Windows prior to Vista, checks a hive for corruption when it loads the hive.
This bug check can also occur if some critical registry keys and values are missing. Thee keys and values might be missing if a user manually edited the registry.
The registry damage is too extensive. You must reinstall the OS or use the Emergency Repair Disk (ERD) that you previously created by using the Windows Backup tool.
Before that I suggest you to create a Windows 10 installation Disc and perform a repair on the computer. To create a please find the below link:

To perform a Repair on the computer, Please follow the below steps:
a. Insert the installation DVD or USB and boot Windows 10 from it.
b. In the
‘Windows setup’ page select the
‘language to install’,‘Time and currency format’ and the ‘keyboard
or input method’ and click on ‘next’.
c. Click on
‘Repair your computer’ and select
‘Troubleshoot’.
d. Click on
‘Advanced options’
and select‘Startup Repair’
and select the operating system.
Hope this information is helpful. Please post in case you have any further issues, I will be glad to help you further.
Thank you.
