No bootable device errors can be incredibly frustrating, especially for those with limited technical expertise. Fortunately, there are a few approaches you can take to fix the problem. This article will provide a step-by-step guide to solving the no bootable device error.
Step 1: Check The Computer’s Power Supply
The first thing to do when attempting to resolve a no bootable device error is to check the computer’s power supply. If the power cord is not firmly plugged in or if the power supply isn’t providing the necessary power, it will prevent the computer from booting. Make sure that the power cord is securely plugged into the wall and the back of the computer. Also, check to make sure the power switch on the back of the unit is turned on.
Step 2: Check The BIOS Settings
If the power looks to be working correctly, then the next step is to check the BIOS settings. The BIOS (Basic Input/Output System) is essentially the control center of a computer and controls how the computer runs. It’s possible that the BIOS settings have been changed and this is preventing the computer from booting correctly. To check the BIOS settings, restart the computer and press the F2 key on the keyboard during the boot process. This will bring up the BIOS settings menu. Check to make sure the settings are correct and that the hard drive is selected as the boot device.
Step 3: Check The Hard Drive Connection
If the BIOS settings look to be correct, then the next step is to check the hard drive connection. The hard drive should be securely connected to the motherboard or SATA controller, and all of the wires connected properly. If the connection appears to be loose or if any of the wires are disconnected, it could cause the no bootable device error. So make sure everything is connected securely and tightly.
Step 4: Check For Evidence Of Damage
If everything looks to be connected properly, the next step is to check for evidence of damage. This can be done by opening up the computer case and looking at the components inside. Look for any obvious signs of damage such as cracked or burned circuit boards or wires. If anything looks damaged, it may need to be replaced and that could resolve the no bootable device error.
Step 5: Test The Hard Drive
If there doesn’t appear to be any signs of physical damage, then the next step is to test the hard drive. This can be done using a variety of different software tools, such as Seagate SeaTools or Western Digital Data Lifeguard Diagnostics. These programs allow you to check the condition of the hard drive and can often identify the source of the problem.
Step 6: Reinstall The Operating System
If the hard drive tests out okay and the problem still isn’t resolved, then the last resort is to reinstall the operating system. This will reset all of the settings and can often solve a wide range of problems. However, it should be noted that this will erase all of the data on the computer and will require an original installation disc or image file.
In conclusion, the no bootable device error can be incredibly frustrating, but there are several approaches to resolving the problem. First, make sure the power supply is working correctly and that the BIOS settings are correct. Next, check the hard drive connection and for evidence of damage. Then, use a diagnostic software tool to test the hard drive. Finally, if none of these steps resolve the issue, a final option is to reinstall the operating system. With these steps, the no bootable device error should be fixed and the computer should be able to boot correctly.
