How to Disable Secure Boot in UEFI for Windows 10 & 11, Dual Boot, and Bootable USB Setup
Are you planning to install Linux or boot from a USB on your Windows PC? You may need to "disable Secure Boot in UEFI". This guide will walk you through the steps to safely "turn off Secure Boot in BIOS" for various purposes like dual boot setup, installing unsigned drivers, or booting from recovery media.
What is Secure Boot in UEFI?
Secure Boot is a security feature found in UEFI (Unified Extensible Firmware Interface) that ensures only trusted software is allowed to boot your computer. It helps prevent malware like rootkits from loading during startup. However, for advanced tasks such as installing Linux or custom OS, you may need to "disable UEFI Secure Boot on Windows 10 & 11".
Why Disable Secure Boot?
- "Dual boot with Linux" – Some Linux distributions won’t install unless Secure Boot is off.
- "Boot from a bootable USB" – Useful for system recovery, OS install, or live Linux USBs.
- "Install unsigned drivers or custom OS" – Secure Boot blocks unsigned or modified software.
Steps to Disable Secure Boot in UEFI
- Restart your PC and press the BIOS/UEFI access key (commonly F2, DEL, ESC, or F10 depending on your brand).
- Enter the UEFI Firmware Settings.
- Navigate to the Boot or Security tab.
- Find the option named Secure Boot.
- Set Secure Boot to Disabled.
- Save changes and exit the BIOS/UEFI interface (usually by pressing F10).
Brand-Specific UEFI Access Keys
- HP: ESC or F10
- Dell: F2
- Acer: F2 or DEL
- Lenovo: F1 or F2
- Asus: DEL or F2
Important Notes
- BitLocker Alert: Disabling Secure Boot may trigger BitLocker recovery in Windows. Backup your recovery key.
- UEFI vs Legacy: Do not change Boot Mode from UEFI to Legacy unless required—it may cause boot issues.
- Enable Later: Once your task is done, you can re-enable Secure Boot for security.
Use Cases for Disabling Secure Boot
1. "Disable Secure Boot for Bootable USB Access"
If you are using a bootable USB to install or repair your operating system, Secure Boot may block it from loading. By "turning off Secure Boot in BIOS", your USB device will be recognized and allowed to boot.
2. "Disable Secure Boot in BIOS for Dual Boot Setup"
Setting up a dual boot system with Linux and Windows often requires disabling Secure Boot, especially for distributions like Ubuntu, Kali Linux, or Arch. With Secure Boot off, GRUB and other bootloaders function correctly.
3. "Disable UEFI Secure Boot on Windows 10 & 11 Easily"
Windows 10 and 11 PCs typically come with Secure Boot enabled by default. It is easy to disable it through BIOS/UEFI. Just remember to re-enable it if you value the added security layer it provides.
Can Secure Boot Be Disabled Permanently?
Yes, but it's not recommended unless you're always working with unsigned software. Secure Boot is an important security feature. Disable it only when necessary and re-enable after completing your task.
What Happens If You Disable Secure Boot?
When Secure Boot is disabled:
- Your PC becomes more vulnerable during boot time.
- You can install any OS or boot from almost any media.
- Windows may alert you or stop certain apps from loading.
My Experience
I recently needed to install Kali Linux on my HP laptop alongside Windows 11. I followed the exact steps above to "disable Secure Boot in UEFI". Initially, I struggled to find the correct BIOS key (F10 for HP), but once I accessed it, disabling Secure Boot was simple. After disabling, my bootable USB was detected instantly. The dual boot setup completed successfully without any Secure Boot interference. Once I confirmed Linux was working fine, I chose to keep Secure Boot off to avoid any future issues. This process taught me the importance of understanding BIOS settings before making changes.
Conclusion
