Windows 10: "boot secure violation invalid signature detected. if this error persists contact a...

Hello,

I'm having a problem while booting the notebook Samsung Model "NP300E5M", I'm using Windows 10 and i wanna know how can I fix this issue ?

"boot secure violation invalid signature detected. if this error persists contact a technic" and then it say to reboot ....after reboot, nothing happend.


I saw another topics and forums that try to solve this issue, and I already tryied to Press F12 (go to the BIOS) and press in "Off" the Secure Boot Control, and nothing changed again.



I tryied format the notebook using a pendrive device but when I boot the notebook using the pendrive the message appers : "Your pc ran into a problem and needs to restart. We'll restart for you"



This problem started to happen when the windows started a new update and the notebook restart, and after this Windows reboot, my notebook did not work anymore.



I tryied everything that I can do, can you help me ? Thanks !

:)
