How to solve the problem that the operating system list is not displayed when the computer starts up

This problem may be caused by the wrong BIOS settings. The cause of the problem is that the operating system disk cannot be recognized. First, try to restore the last correct configuration in the BIOS. If you can't find the last correct configuration option to restore, set the hard disk where the system is located to the first boot disk in the BIOS boot settings.

Operating system damage: The operating system file may have been damaged, resulting in the inability to start. You can try to repair or reinstall the operating system using the operating system installation medium (such as installation disc or USB drive).

To solve this problem, you can try the following methods: Check the hard disk connection: plug and unplug the hard disk power cable and data cable again to ensure that the connection is good.Repair with Windows installation disk: Insert the Windows installation disk into the computer, enter the installer, select "Repair Your Computer", and then select "Start Repair".

Operating system or boot file damage: This is one of the most common reasons. During the startup process, if there is a problem with the operating system file or boot file, the computer may not be able to load the operating system correctly. Hard disk failure: If your hard disk fails, such as bad channel or physical damage, the computer will not be able to find the operating system.

The error prompt of Missing operating system usually indicates that the computer cannot find the hard drive with the operating system. The following is a possible solution: check whether the hard drive is connected properly.Open the computer case and check whether all cable connections are intact.

Check the boot order: When the computer starts, press the F12 or Del key to enter the BIOS and check whether the boot order is set correctly. The hard disk where the operating system is located should be in the first place in the boot order.
