Most computers today have a feature called Secure Boot. This feature serves to prevent the computer from firmware or operating systems that are not known by Microsoft, so this feature can protect you from malware or similar programs that attack through the boot process.
But in some cases, you may need to turn off Secure Boot. For example, if you want to install the Linux operating system, which is not known by Microsoft. So it is necessary to turn off Secure Boot so that the computer can boot into the Linux installation.
