Method 1: Update all your available drivers 

Many blue screen errors are blamed on outdated, corrupted or missing device drivers. BAD_SYSTEM_CONFIG_INFO is no exception. You probably can solve this problem through updating all your available drivers on your Windows.

To update your drivers, you should verify that all your devices have the right drivers, and update those that don’t. You can do it manually: Go to the manufacturer’s website for your devices, and search for the most recent correct driver. Be sure to choose only drivers that are compatible with your variant of Windows versions. In this way, you will need to check the update for your devices one by one.

If you’re not comfortable playing around with drivers manually, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):

1) Download and install Driver Easy.

2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3) Click the Update button next to a specific driver to automatically download and install the correct version of this driver (you can do this with the FREE version).

Or click 
Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).

4) Reboot your Windows 10 to see if it works.

Method 2. Fix the BCD file

    you 1st have to find what letter is your windows hard drive. On mine it’s partition E.
    You can find it by doing this:
    c:
    dir
    If you can see the windows folder, then it’s C:
    If not, continue procedure until u find the right one:
    d:
    dir
    yes? / no ?
    no=continue:
    e:
    dir
    until you find a HDD with a windows folder.

    Unfortunately the methods above have not worked above (even replacing the windows reg files with the RegBack files). Each time my windows load, or repair loads the PC shuts down. (even on safe mode)
    There seems to be a GPU driver error and as soon it goes in to windows, boom!
    It can stay for hours on the cm or bios. So it’s a big windows bug, which I believe will only go away with reformatting/reinstalling Win10 and loosing all the installed programs and settings !!
    What a waste of time these BUGS !!

    If anyone has found a solution to this, plz let me know.

      I don’t know whether this is OS , updates issue or h.disk issue !?!
