To protect Windows from the malware, Secure Boot plays an important role when Windows boots. UEFI (Unified Extensible Firmware Interface) defines a theory of the “Secure Boot”, UEFI replaces BIOS (Legacy Basic Input/Output System) and provides an interface between the operating system and hardware firmware.
Unified Extensible Firmware Interface (UEFI) is the next generation over the BIOS that supports PC repair, remote diagnostics, etc. UEFI is faster and has more features that BIOS, It is just like a tiny software that runs when PC starts.
When Secure Boot is enabled, Only firmware or software assigned with private keys are allowed to run. Because of that, Sometimes Software and firmware not assigned with private keys are not allowed.
When the system could not approve the assigned key, Because of that Secure Boot doesn’t allow us to run the software. In such a situation, You can Disable Secure Boot in Windows using the UEFI specification.
Disable Secure Boot in Windows 10
This process will not be too easy but not too hard, You can not disable Secure Boot using Windows settings. This is to be done by using UEFI firmware settings. You have to follow all the steps carefully.
1. First of all, You have to boot your PC with BIOS utility, You can go to Windows 10 Settings and Reboot your PC with Advanced Startup under the Windows Recovery, this will take you to the Advanced Startup settings.
Alternatively, You can reboot your PC then press the F11 or F12 key or whatever key your PC supports to open the BIOS settings.
If you’re not able to open BIOS settings through these options. You have to start and shut down your PC 3-4 times and at every booting time keep pressing the ESC key repeatedly will take you to the Advanced Startup option.
2. Now, you will get some options under the Advanced Startup, Go to the Troubleshoot>Advanced Options.
3. Under the Advanced option go to the UEFI Firmware settings, and restart your PC.
4. This opens the BIOS settings manager where you can get Boot related settings. Navigate the Security tab and go to secure boot and set it to disable mode, then Save&Exit settings.
Every OEM has its own priority of implementing these options, but mostly you can disable Secure Boot under the Security section or Boot section.
5. Once Secure Boot is disabled, you can install any program or whatever you want.
Recommendation: BIOS is an Advanced user option. If you know well what you’re going to do then use these options otherwise this might be a cause of any system error. If you have disabled Secure Boot, this might possible you can not enable it without resetting the Windows to the factory state.
