Windows 10 stuck in blue screen reboot

Windows 10 is stuck in blue screen reboot. New drivers were installed then the blue screen popped up showing the stopcode Page_fault_in_nonpaged_area

When the pc tries to reboot it will get just past the home screen load up then the blue screen will appear again. It will do this 3 times then go into automatic repair then start diagnosing and attempting to repair. I cannot get to the advanced options menu.
Please help!!

windows 10 no advanced-startup-options, so no startup settings

when i did 1. 2. 3. steps i checked and problem was SOLVED
but after 4. 5. 6. 7. steps i checked and no advanced startup options again

1. Make a complete backup image of your current HD including all partitions to an external HD using macrium reflect . Once done, disconnect all USB devices from the PC. Assuming now you only have one HD connected to the PC which you will be installing Windows.
   IMPORTANT: Also create a Macrium Rescue disk to boot from later on.
2. Boot up your Windows installation USB/DVD. On the first screen, Hold SHIFT + F10 to open Command Windows then type:
   Diskpart
   select disk 0
   clean
   exit
3. Click Next, Choose Custom, select the unallocated partition then click Next (Do not format), when asked for Product ID key, click on "Skip this step"/"Do it later". Continue the Installation.
4. Once done. With the external HD connected, Reboot your PC with the Macrium Rescue disk, select the image that you created in step 1 as the Source.
5. Select your current HD/SSD as Destination disk
6. Restore only C: Drive to it. ie. overwrite the new C: Drive with your backup C: Drive.
   NOTE: See screen shot on how to perform this step
7. Disconnect all the external devices. Reboot. Windows should perform a startup repair.

but after step 7 i checked key and it was not the same which i purchased, why did that change? i activated purchased key again.
