Are you staring at a blank screen with an error message that reads, “No bootable devices found” or “No boot device available”? You’re not alone. This frustrating issue can occur on any computer, whether it’s a Windows PC, a MacBook, or a Linux machine. In this article, we’ll delve into the possible reasons behind this problem and provide you with step-by-step solutions to get your system up and running again.
Understanding the Boot Process
Before we dive into the troubleshooting process, it’s essential to understand how the boot process works. When you turn on your computer, the BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) firmware is activated. The BIOS/UEFI checks the system’s hardware components, including the hard drive, solid-state drive (SSD), or other storage devices. It then searches for a bootable device, which is a device that contains a valid operating system.
The BIOS/UEFI follows a specific order when searching for a bootable device, known as the boot order. The typical boot order is:
- USB drives
- CD/DVD drives
- Hard drives or SSDs
If the BIOS/UEFI can’t find a bootable device, it will display an error message, and the system will not boot.
