To ensure that Windows 10 remains protected against malware, Microsoft has enabled support for Secure Boot, which works via UEFI. Secure Boot ensures that your PC only uses firmware that the manufacturer trusts at boot time. However, in many cases, you will need to disable Secure Boot on Windows 10 due to incorrect hardware configurations.
If you wonder what the UEFI is, it extends to the unified extensible firmware interface and is the next generation of popular BIOS. It is secure, can store more data, much faster than the BIOS and is almost like a tiny operating system that runs on the PC firmware, and it can store much more than a BIOS. Best part, it can be updated by OEM via Windows Update.
With UEFI, Windows 10 offers security features such as Secure Boot, Windows Defender Device Guard, Windows Defender Credential Guard, Windows Defender Credential Guard and Windows Defender Exploit Guard. You will find below a list of the functions you receive:
- Faster start and restart times.
- It easily supports large hard disks (over 2 terabytes) and disks with more than four partitions.
- Multicast deployment support that allows PC manufacturers to transfer a PC image that can be received by multiple PCs without overloading the network or image server.
- Support for optional UEFI firmware drivers, applications and ROMs.
Disable secure boot under Windows 10
Just before disabling secure boot because you can, let us know if your PC has a secure boot.
Open the Windows Defender Security Center and click Device Security.
If Secure Boot is mentioned in the next screen, then your PC has it, otherwise not. If it is available, you know if it is actually turned on for your PC. We recommend that you turn it on.
If you want to have Secure Boot on your PC, you must purchase a new one from the OEM that supports it.
Suppose you have Secure Boot, and it is enabled, let’s see how to disable it. Be sure to read the entire manual, especially the warnings at the end of the article.

You can then replace your graphics card or any other equipment that you feel is causing you problems. Be sure to perform the same steps again and enable secure boot this time.
Warning when disabling Secure Boot
After disabling Secure Boot and installing other software and hardware, it may be difficult to reactivate Secure Boot without resetting the PC to factory defaults. Also be careful when changing BIOS settings. The BIOS menu is intended for advanced users, and it is possible to change a setting that might prevent your PC from booting properly. Be sure to follow the manufacturer’s instructions carefully.
