1. Shut down the computer and open the computer case.
2. Verify that the SATA cable is firmly and properly connected to both the motherboard and the hard drive.
3. Reboot the computer.

Fix 3. Set the Bootable Hard Disk Order

Suppose you have an unbootable disk inserted in your Acer computer, or you haven't configured the bootable disk as the primary startup option. In that scenario, you might encounter issues with Windows failing to boot on your Acer device. To guarantee smooth booting of your computer, you need to modify the boot order and set the disk containing the operating system as the boot device.

Step 1. Restart your computer and press F10 repeatedly to enter the BIOS setup menu.

Step 2. Open the Boot menu and use "+" or "-" to move the hard drive.

Step 3. Press F10 to save the changes to the boot sequence and exit.

Step 4. Restart the computer.

Solution 4: Repair Damaged MBR

The Master Boot Record (MBR) functions as the boot sector of the hard disk, storing crucial information about the disk's partitions and responsible for loading the operating system. Corruption of the MBR can occur due to viruses or bad sectors on the hard drive, resulting in the inability to boot Windows and the appearance of an Acer "no bootable device" error.

You can effortlessly repair a corrupted MBR using tools Partition Master, an advanced disk management utility. This software enables you to create bootable USB drives effortlessly and rebuild the MBR within a WinPE environment.

Step 1. Create a WinPE bootable disk

1. Launch tools Partition Master and click "Bootable Media" from the toolbar. Select "Create Bootable Media." 2. Click "Next" to complete the process.

Step 2. Boot the Partition Master Bootable USB

Connect the bootable USB or CD/DVD to your PC. Restart your computer and press F2 or Del to enter the BIOS screen. Set the boot order to "Removable Devices" or "CD-ROM Drive," then save and exit. The Partition Master tool will run automatically.

Step 3. Rebuild MBR

Select the disk and the type of MBR you want to rebuild, and then click "Rebuild".

Then you'll see "MBR has been successfully rebuilt on Disk X".

Other issues that Partition Master tools can address:

Fix 5: Set the Primary Partition as Active

Acer also fails to boot the device if the primary partition is not "active." To resolve this, you need to boot the computer using the Windows installation media. Follow these steps to set the primary partition using Diskpart: 1. Insert the Windows installation media (DVD or USB) and restart your Acer device. 2. Press the appropriate key (usually F2, F10, F12, or Esc) during startup to enter the Boot Menu. 3. Select the USB/DVD drive as the boot device and press Enter. 4. The Windows Setup will appear. Instead of clicking "Install Now," click on "Repair your computer" located at the bottom left corner. 5. Choose "Troubleshoot" > "Advanced options" > "Command Prompt." 6. In the Command Prompt, type `diskpart` and press Enter. This will launch the Diskpart utility. 7. Type `list disk` and press Enter to view all available disks on your system. 8. Identify the correct disk containing your Windows installation (usually Disk 0). Type `select disk X`, replacing 'X' with the disk number and press Enter. 9. Type `list partition` and press Enter to view the partitions on the selected disk. 10. Identify the primary partition (usually Partition 1) and note its number. Type `select partition Y`, replacing 'Y' with the partition number, and press Enter. 11. Finally, activate the partition by typing `active` and pressing Enter. After completing these steps, exit the Command Prompt, and the computer should automatically reboot. It should now boot from the active primary partition. If the issue persists, you may need further assistance or consider additional troubleshooting steps.

Step 1. Create a Windows installation disc and boot your computer system from it.

Step 2. Choose the language and region, then click "Repair your computer."

Step 3. Open Command Prompt:

For Windows 7: Under "System Recovery Options," select Windows 7, click "Next," and then "Command Prompt."

Step 4. Enter each of the following commands one by one:

• diskpart
• select disk 0
• list partition 1
• active

Step 5. Restart your computer after closing the Command Prompt.

Fix 6: Repair File System on Bootable Drive

Corruption in the file system of the boot disk can also lead to the hard disk not booting properly. You can attempt to repair the corrupted file system using the CHKDSK command.

Step 1. Access the command prompt by starting your computer from the above Windows installation disk.

Step 2. Enter the following command:

chkdsk E: /f /r /x ("E" signifies the drive letter of the partition to be repaired)

Fix 7. Repair Corrupted Boot Files

Corrupted startup files on Acer computers can also lead to errors. To address this, you can run the SFC/DISM command to scan and fix corrupted system files.

Use the Windows Installation CD to start the command prompt and type in the following command:

sfc /scannow /offbootdir=c: /offwindir=c:windows This command translates to: "Run the System File Checker (SFC) utility to scan and repair system files, using the operating system directory on drive C: (C:\Windows) and the boot directory also on drive C: (C:\)."

If this command doesn't resolve the issue, try using a DISM scan:

DISM /Online /Cleanup-Image /RestoreHealth This command translates to: Deployment Image Servicing and Management (DISM) /Online /Cleanup-Image /RestoreHealth This is a command used in Windows operating systems to repair the system files by using the System File Checker (SFC) tool. It helps to restore the health of the Windows image by fixing any corrupted or missing system files. The parameters mean: - /Online:指的是对正在运行的操作系统进行操作。 - /Cleanup-Image:表示要清理或修复映像文件。 - /RestoreHealth:意味着恢复映像到健康状态，通过从Windows Update或Microsoft Update服务器下载并安装缺失或损坏的系统文件。

If this doesn't work, keep trying:

Dism /Image:C:\offline /Cleanup-Image /RestoreHealth /Source:c:\testmount\windows

Dism /Online /Cleanup-Image /RestoreHealth /Source:c:\testmount\windows /LimitAccess

Solution 8: Recover Lost Boot Partitions

An Acer "no bootable device" error may also occur if your system partition has been accidentally deleted. If you have created a bootable USB using the Partition Master tools in Fix 4, you can utilize the tool to successfully recover the lost partition.

Step 1. Open tools Partition Master and click "Partition Recovery". Select the target disk with your lost partition and click "New Scan".

Step 2. Wait patiently for the software to execute the "Quick Scan" and "Full Scan" operations. It will mark your deleted partition as "lost" under the Status section. Select the lost partition and click "Recover."

You can also double-click the partition you're looking for to preview its content, then click "OK" to confirm.

Step 3. Wait patiently and click "Done" when the partition recovery process is finished.
