How to set startup items when booting without a USB flash drive

What to do if the startup item does not boot from the USB disk

When we use the computer daily, sometimes we encounter some problems, such as system crashes or the need to reinstall the operating system. At this time, we often choose to use a USB flash drive to start the system. However, sometimes we may find that the U disk option does not appear in the computer's startup items, which makes it impossible for us to start the computer through the U disk. So, how should we respond when the startup item does not boot from the USB flash drive? This article will introduce you to some solutions.

First, we can check the BIOS settings. BIOS (Basic Input/Output System) is a program that runs when the computer starts. It is responsible for initializing hardware devices and loading the operating system. In the BIOS settings, we can adjust the computer's boot sequence to ensure that the USB flash drive is correctly recognized as a boot device. The specific steps are as follows:

1. First, we need to restart the computer and enter the BIOS setting interface. Under normal circumstances, you can enter BIOS settings by pressing the "DEL", "F2", "F10" or "ESC" key. The specific key to use to enter the BIOS depends on the brand and model of the computer. You can pay attention to the prompt information on the screen when booting.

2. After entering the BIOS settings, find the "Boot" or "Startup" option. This option is usually located at the top or bottom of the navigation menu.

3. In the startup options, we need to find the "Boot Priority" or "Boot Sequence" setting item. These items usually have the order in which each boot device is listed below them. We can adjust the order of the devices by using the up and down arrow keys to ensure that the USB flash drive is before other devices.

4. After the adjustment is completed, press the "F10" key to save the settings and exit the BIOS. At this point, the computer will start according to the startup sequence we just set.

If there is still no U disk boot option after adjusting the BIOS settings, we can try other methods, such as using CD/DVD to boot. The specific steps are as follows:

1. Prepare a bootable system CD or system installation disk. This disk can be a Windows system installation disk, Linux system disk or other system recovery disk.

2. Insert the startup disk into the computer's optical drive.

3. Restart the computer and enter the BIOS setting interface. The method is the same as mentioned above.

4. In the BIOS setting interface, we need to find the "Boot" or "Startup" option, and then select CD/DVD as the boot device.

5. Save the settings and exit the BIOS. At this time, the computer will boot from the startup disk in the optical drive.

Of course, if we need to use a U disk to start urgently, but there is still no U disk option in the computer's startup items, we can also try to solve the problem by restarting the computer. The specific steps are as follows:

1. Insert the U disk into the USB interface of the computer.

2. When the computer is running, press the "Ctrl", "Alt" and "Delete" keys to restart the computer at the same time.

3. After restarting, the computer's BIOS may re-detect the USB flash drive and display it in the startup items.

4. At this time, we can adjust the startup sequence as mentioned above to ensure that the U disk is set as the preferred startup device.

Through the above method, we can solve the problem that the startup item does not start from the USB disk. However, before doing anything, we need to err on the side of caution and back up important data. At the same time, if we are not sure whether our operation is correct, it is best to consult professionals to avoid unnecessary losses. Only correct operations and appropriate solutions can allow us to better solve the problem and start the computer smoothly.
