Got it to work after reading and trying and almost throwing the laptop away.
1. Go to System Restore and then Command Prompt (if windows 8 or 10 is preinstalled, start windows and click start and type System Restore.
2. Type Diskpart, list Disk, select disk 0 (in my case), clean. After that simply type exit and exit and restart to your CD or USB. I am soooo happy now. hope it helps you guys.
