Today we will talk about what Secure Boot is. How to disable this element and why it is needed, we will consider further. We are talking about hardware configuration software that is used today instead of BIOS on various motherboards.
General information
We have already determined what Secure Boot is. How to disable this element is a question that becomes especially relevant if the function interferes with loading from a flash drive or disk during the installation of Windows or another operating system. There are several other situations where deactivation may be necessary, but they are less common. A very common case is when a message appears on the main desktop indicating that Secure Boot is not configured correctly. How to disable this notification, we will also tell. In many ways, the deactivation procedure depends on the UEFI interface. Therefore, recommendations for several options will be described below.
Parameters
First of all, let's move on to the UEFI settings. In other words, we go into the BIOS of the computer. There is the following method for this:
- If Windows 8 or 8.1 is installed on the PC, go to the right panel and select the "Options" item.
- Next, we are waiting for the opening of the next menu and go to the tab “Change settings”.
- We use the "Update and Restore" function.
- We are waiting for the launch of this tool and select "Recovery".
- Click the "Reboot" button.
- Then we go to the “Advanced Settings”, and then to the “UEFI Software Settings”.
- The computer will reboot and display the necessary settings.
Delete
We continue to discuss the Secure Boot feature. How to disable it, you can understand only after entering the BIOS. The first option to run this item has been described above. But a similar result can be achieved in another way. While turning on the desktop computer, click Delete. To solve the issue of how to disable Secure Boot on a Lenovo laptop, you may need another key: most often F2. Pay attention to the initial screen when you turn it on. It often indicates the button we need.
Deactivation Example
Next, we will detail how to disable Secure Boot on an Asus laptop. This instruction can be considered universal, since it is suitable for most other motherboards that support the function of interest to us.
- So, go to the “Download” tab and find Secure Boot.
- Go to the OS Type item and install Other OS.
- After that, save the settings - as a rule, the F10 key is responsible for this.
- On certain types of motherboards from Asus for this purpose, go to the Security or Boot tab, then set the Secure Boot parameter to Disabled. The task is complicated by the fact that the function of interest to us, as a rule, cannot be disabled at basic settings. Switching between Enabled and Disabled is not available.
- To make the change available in the Security section, if necessary, set a password using Set Supervisor Password. Only then do we turn off secure boot.
- Additionally, you may need to activate Legacy Mode or CSM boot mode instead of UEFI. On certain motherboards from Gigabyte, disabling Secure Boot mode is available in the BIOS Settings section.
To start a personal computer from a USB flash drive, you also need to activate the CSM download and the previous version of the inclusion. On most computers and laptops, the described options for finding the required function work. Certain details may change, but the described algorithm remains constant. For example, on some HP notebook models, you need to go to the System Configuration section. Next, select the Boot Options item. In the menu that appears, find Secure Boot.
It should also be briefly said about Acer laptops. In them, the function of interest to us is deactivated through the Authentication section. You may need to go to Advanced and then open System Configuration to achieve the result.
