For example: if you want to launch a program while having a USB device not known to be connected, an "security box security" error will appear, and it is normal because Windows is designed to destroy only when a trusted firmware (digitally signed). However, there are times when we may have to do it because we need to do some tests or because we have problems, so we will show you how to do it.
How to enable and disable UEFI Safe Boot
The first thing to do is start the program in boot boot mode, and in this case from Windows 10 you have to go into the menu configuration -> Update and security -> Update. There you will see a button, under Advanced Start, which gives us the "Refresh Now" option.
The program will restart and a green screen will appear that will allow you to choose between multiple options. In the first case we will select "Problems."
In the following, Advanced Options.
Within the advanced options, we have to go to the last option: UEFI firmware configuration.
After rendering it, the system will inform us that the device will be restarted, and after pressing the reboot button will do just that.
When restarting, the computer will enter the BIOS without touching anything. There, we should go to the Boot section and select Secure Boot.
Here we will see whether it is activated or not, and its parameters. However, it will not let us touch anything, because in order to enable the options to be enabled we must first take the first step, which is to establish BIOS admin password.
To do this, we must go to the BIOS security section.
In Administrator Password, press and request to enter a password.
We present, and voila. After that we can go back to the Safe Mode menu and turn it off when we need it, or activate it when we have it (optional).
By the way, if you change the Standard Optimal parameter, it is highly recommended retrieve the BIOS password again, because if we lose or don't remember we can have serious problems re-accessing the configuration. To do this, we must simply follow the steps behind; the system will ask us to enter the current password, and in the new one we simply leave it blank
What do we achieve by enabling and disabling the UEFI Safe Boot?
The first goal of the UEFI Secure Boot to protect the system from unauthorized boot loaders, especially those that may come from malicious code similar to those we sometimes get at the risk of the processor. At the same time, turning on this mode will give us great power on the PC, since turning it off can cause problems if, for example, we leave the USB flash drive connected to the computer bootloader when we start it.
As we have the option to activate it, on the other hand, it will allow us to perform tests that we deem appropriate for the machines, and modify what we want, although it is true that these are conditions for highly developed users who want to perform specific tasks in a group.
