The BIOS (Basic Input Output System) is the first software loaded at boot time, which is responsible for initializing and detecting the hardware device, as well as booting the operating system. This topic describes how to set the startup item to PCIe via BIOS.
Demo environment: Honor MagicBook 16 Pro, Windows 10
First, you need to restart your computer and go to the BIOS settings screen. Different brands of computers may have different ways to access the BIOS, but it is usually when the computer boots up by pressing a specific key, such as F2, F10, Delete, etc. If you're not sure how to get to the BIOS setup screen, you can check the prompt on the screen when your computer boots up.
In the BIOS settings screen, you will need to find the Boot Options or similar. This option is usually in the "Advanced" or "Boot" menu. In this menu, you can see a list of various boot devices, such as hard drives, optical drives, USB devices, etc.
In the list of boot options, locate the PCIe device and set it as a boot item. The exact method may vary depending on the BIOS version, but it is usually to move the PCIe device to the top of the list or to select it and press a specific button such as F5 or F6 to move it to the top. When setting up a PCIe device as a boot item, you need to make sure that the device is properly installed and connected to the PCIe slot on the motherboard.
After setting up the PCIe device as a boot item, you need to save the settings and exit the BIOS. The exact method may vary depending on the BIOS version, but it is usually by pressing the F10 or similar button to save the settings and exit the BIOS. Before exiting the BIOS settings, you can check if other settings are correct, such as time, date, etc.
Once the setup is complete, restart your computer and test if it is able to boot from your PCIe device. If everything is fine, the computer should be able to boot up and load the operating system from the PCIe device. If there is a problem during the test boot, you may need to check that the PCIe device and motherboard are connected properly and reset the boot options in the BIOS.
It should be noted that you should be careful when making settings in the BIOS and do not change other settings at will, so as not to affect the stability and normal operation of the system. If you're not sure how to set it up, you can consult the relevant manual or consult a professional first.
