Why do you ask what you're to do when you get into Safe Mode when the very first step
in the tutorial is to enter Safe Mode with networking to install Malwarebytes to do a full scan?
How many times do I need to ask you if you're following the steps in Troubleshooting Windows 7 Failure to Boot?
Don't wonder why nothing is working. You haven't even begun to follow the steps and just ignore reminders on how to do them.
If you have questions on how to do any of the steps in order (1,2,3,4,5, etc) then ask back about that.
