What does the “No Boot Device Found” error mean on a Dell laptop?
The “No Boot Device Found” error on a Dell laptop indicates that the computer is unable to locate a bootable device, such as a hard drive or solid-state drive (SSD), to load the operating system. This error can occur due to various reasons, including a faulty or disconnected hard drive, a corrupted boot sector, or a misconfigured BIOS setting.
To resolve this issue, you need to identify the root cause of the problem. Start by checking the physical connections of your hard drive or SSD to ensure they are securely connected to the motherboard. If the connections are loose, try reconnecting them and see if the error persists. If the issue is not related to physical connections, you may need to investigate further to determine the cause.
How do I troubleshoot the “No Boot Device Found” error on my Dell laptop?
To troubleshoot the “No Boot Device Found” error on your Dell laptop, start by restarting your computer and entering the BIOS setup.
