Are you frustrated when your computer won't boot and displays the message "No bootable devices found"?

Hard drive is not set as first boot device in BIOS
In this case, you can simply change boot order like this:
1. Restart computer and tap Del to enter BIOS interface.
2. To change the boot order, press the right arrow key until the "Boot" tab is selected, then use the "+" or "-" button to move "Hard Drive" to the top of the list.
3. Press F10 to save changes and restart computer.
Tips:
● The function key to enter BIOS interface is typically F1, F2, F3, Esc, or Delete, and can be found in your PC manufacturer's manual or online documentation.
● The BIOS setup utility's menu option or configuration item for setting the boot order may be called something different in each utility, such as Boot, Boot Options, Boot Order, etc., and may be located within a general menu option like Advanced Options, Advanced BIOS Features, or Other Options.
Corrupted MBR
To repair a corrupted MBR in Windows 10, you can try the following steps:
1. To install Windows, you need to boot from the Windows installation media. This typically involves inserting a USB drive or CD/DVD that contains the Windows installation files into your computer, and then configuring your computer's BIOS or UEFI settings to prioritize the installation media as the boot device.
2. To repair your computer, select the language and region, and then click on "Repair your computer" when you see the "Install now" window.
3. On the Advanced options screen, select Troubleshoot and then Command Prompt.
4. In Command Prompt, input following command lines and press Enter after each. (If you are asked whether you want to add a new installation to boot list, type "y" and then press Enter.)
● bootrec /fixmbr
● bootrec /fixboot
● bootrec /scanos
● bootrec /rebuildbcd
5. Exit Command Prompt and restart your computer.
Solve no bootable device found with free partition manager
If the Master Boot Record (MBR) of your computer is corrupted, you can use a reliable partition manager called Qiling Disk Master Standard to rebuild the MBR. This software is free and can help you fix the issue with the "no bootable device" error in Windows 10. To do this, you can follow the steps provided by Qiling Disk Master Standard to rebuild the MBR and get your computer up and running again.
Step 1. Connect a USB drive to a computer in good condition, download, install and run Qiling Disk Master, then click on "Tools" > "Make Bootable Media" on the main interface and follow the wizard to create a bootable USB drive.
Tips: The bootable USB will contain installed Qiling Disk Master.
Step 2. To fix a computer with a boot problem, insert a bootable USB drive into the computer, then enter the computer's BIOS settings and change the boot order to prioritize the USB drive. This allows the computer to boot from the USB drive instead of its internal storage, allowing you to access the computer's operating system and potentially troubleshoot or repair the boot issue.
Step 3. Once logged in, you'll see the Qiling Disk Master loaded. Right-click the system disk, then select "Rebuild MBR".
Step 4. The type of MBR for Windows 10 should be set to "BIOS" in the pop-up window. This will ensure that the system can boot properly and that the MBR is compatible with the Windows 10 operating system.
Step 5. You can restart your computer later after clicking "Proceed" to commit the pending operations.
Summary
If you encounter the "no bootable device found" issue in Windows 10, the solutions also apply to Windows 7. If data loss occurs during the process, you can use the "Recover Data" function to retrieve lost data. Additionally, you can use Qiling Disk Master to perform various operations such as rebuilding MBR, increasing C drive memory, or erasing an SSD before selling.
