Solutions to resolve “No bootable device” error

To resolve this error in Acer, you can use the following methods, highly recommended by computer experts.

Solution 1: Change the boot order

If you insert a non-bootable disc or CD into the Acer computer and set it as the boot device, you will not encounter a "bootable device". Therefore, to ensure that the computer starts up correctly, you must change the boot order and set the disk that loads the operating system as a bootable device. To change the boot order, follow these steps:

  1. Press the power button and hold F10 to access the BIOS. (The key can be ESC, Delete, F1, F2, depending on the computer you are using)
  2. Press the arrow key on your keyboard to get the Boot tab, and then change the boot order settings to make the hard disk the first boot device.
  3. Follow the instructions given in the BIOS utility to access the Exit tab.
  4. Find and choose the Exit Saving Changes option to exit the changes made to the boot sequence.
  5. Follow the instructions to restart your computer. If the problem is still not resolved, see the following solution.

Solution 2: Reset primary partition as active

If the primary partition is not defined as "active", the non-bootable device will occur in Acer. Please reset your primary partition as active using Diskpart and running some commands.

First, insert the Windows installation media (DVD or USB key) and start your computer from it, then under System Recovery Options or Troubleshooting, click Command Prompt, type the following commands in sequence , then press Enter after each: select disk 0 -> partition list 1 -> active.

Solution 3: Repair corrupted boot files

Corrupted boot files on Acer computers may be another important reason for the error explained, such as the corrupted MBR. You can try to repair the MBR to get rid of any bootable device problem. Take these steps:

  1. Insert the boot disk into your computer and boot from it.
  2. Select the language and region, and then click Repair your computer.
  3. On a Windows 10 installation media (or Windows 8.1, Windows 8), select Troubleshooting, then Command Prompt. On a Windows 7 installation media, in the System Recovery options, select the first item and Windows 7 as the operating system, click Next, and then click Command Prompt.
  4. In the command prompt, type the following commands one by one and press Enter after each command. (If you are asked if you want to add a new installation to the startup list, press Y, then press Enter.) bootrec / fixmbr bootrec / fixboot bootrec / scanos bootrec / rebuildbcd
