Are you frustrated with your Acer laptop or desktop refusing to boot, displaying the dreaded “No Bootable Device” error message? You’re not alone. This issue can be caused by a variety of factors, including a faulty boot order, corrupted boot files, or a malfunctioning hard drive. In this comprehensive guide, we’ll walk you through the process of troubleshooting and fixing the “No Bootable Device” error on your Acer device without relying on legacy boot modes.
Understanding The “No Bootable Device” Error
Before we dive into the solutions, it’s essential to understand what the “No Bootable Device” error means. This error message typically appears when your computer’s BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) is unable to detect a bootable device, such as a hard drive or solid-state drive (SSD). This can be due to a variety of reasons, including:
- A faulty or disconnected hard drive or SSD
- A corrupted boot sector or master boot record (MBR)
- A misconfigured boot order in the BIOS or UEFI settings
- A malfunctioning BIOS or UEFI firmware
Preparation Is Key
Before attempting to fix the “No Bootable Device” error, make sure you have the following:
- A valid Windows installation media (USB or DVD)
- A backup of your important files and data (if possible)
- A basic understanding of computer hardware and BIOS/UEFI settings
Troubleshooting The “No Bootable Device” Error
Let’s start by troubleshooting the issue. Follow these steps:
Step 1: Check The Boot Order
The first step is to ensure that the boot order is set correctly in the BIOS or UEFI settings. To do this:
- Restart your Acer device and press the key to enter the BIOS or UEFI settings (usually F2, F12, or Del)
- Navigate to the Boot tab and ensure that the hard drive or SSD is set as the first boot device
- Save the changes and exit the BIOS or UEFI settings
Step 2: Verify The Hard Drive Or SSD Connection
Next, verify that the hard drive or SSD is properly connected to the motherboard. If you’re using a laptop, ensure that the hard drive or SSD is securely connected to the motherboard. If you’re using a desktop, check that the SATA cables are securely connected to the motherboard and the hard drive or SSD.
Step 3: Run A Diagnostic Test
Run a diagnostic test on the hard drive or SSD to identify any potential issues. You can use the built-in Check Disk (chkdsk) utility in Windows or a third-party diagnostic tool.
Fixing The “No Bootable Device” Error
If the troubleshooting steps above don’t resolve the issue, it’s time to try some more advanced solutions.
Method 1: Rebuild The Boot Configuration Data (BCD)

bootrec /fixmbrbootrec /fixbootbootrec /rebuildbcd
- Restart your Acer device and see if the issue is resolved
Method 2: Perform A System Restore
If the issue started after a recent software or driver update, you can try performing a System Restore to revert your system to a previous state. To do this:
- Insert the Windows installation media and restart your Acer device
- Press the key to enter the BIOS or UEFI settings and set the Windows installation media as the first boot device
- Save the changes and exit the BIOS or UEFI settings
- Follow the prompts to boot from the Windows installation media
- Open the Command Prompt and type the following command:
rstrui.exe
- Follow the prompts to select a restore point and complete the System Restore process
Method 3: Reinstall The Windows Boot Loader
If the above methods don’t work, you can try reinstalling the Windows Boot Loader. To do this:
- Insert the Windows installation media and restart your Acer device
- Press the key to enter the BIOS or UEFI settings and set the Windows installation media as the first boot device
- Save the changes and exit the BIOS or UEFI settings
- Follow the prompts to boot from the Windows installation media
- Open the Command Prompt and type the following command:
bootrec /fixboot
- Restart your Acer device and see if the issue is resolved
