Please install an operating system to your hard disk.” In this situation, you can change the boot order in BIOS and let it boot from the bootable device. To do so, follow the steps given below:

• Restart the computer and then repeatedly press the F10 key to enter the BIOS setup menu.
• After opening BIOS, go to the boot settings.
  • Notebook Computers: Select Storage > Boot Options.
  • Desktop computers: Select System Configuration > Boot Options.

• Proceed with the on-screen instructions to change the boot order.

Method 2: Perform Hard Reset

When you reset the device, it forces the system to clear and reestablish the software connections between the BIOS and the hardware. To perform a hard reset, follow the steps listed below:

• Turn off the computer and remove it from any port replicator or docking station.
• Disconnect all external devices from your computer and unplug the AC adapter. Remove the battery as well.
• Press and hold the Power button for about 15 seconds.
• Then, insert the battery and plug the AC adapter back into the computer.

Note: Don’t connect any of the peripheral devices, such as USB storage devices, external displays, printers, etc.

• Now, turn on the computer. When the start menu opens, use arrow keys to select  Start Windows  Normally; press  Enter .

Method 3: Restore BIOS to Default Settings

It may be the case that your system is configured to boot from an unbootable disk. In such a scenario, resetting your BIOS will restore it to the last saved configuration. To do so, follow these steps:

• Turn off the computer.
• Wait for at least 5 seconds and then restart the computer. Repeatedly press the F10 key to enter the BIOS setup menu.
• On the BIOS setup screen, press F9 to select and load the BIOS Setup Default settings.
• Press F10 to Save and Exit.
• Select  Yes , then press  Enter  when asked to Save Changes.
• Finally, follow the prompt to restart the computer.

If the computer restarts normally, it means that the issue is fixed. If it still displays the “boot device not found” error message, proceed to the next method.

Method 4: Fix and Rebuild Damaged MBR

If the MBR is damaged or has some other issue, you may encounter the ”Boot device not found 3F0 error.” You can fix it by following the steps below:

• Press F8 while booting and check if you can get to Windows Recovery. Once there, go to Advanced -> Command Prompt. If you are unable to do so, you’ll need a bootable ISO.
• In the Command Prompt Window, enter the following commands:
  • bootrec /RebuildBcd
  • bootrec /fixMbr
  • bootrec /fixboot

• Now reboot and check for the error status.

If the above steps didn’t fix the hard disk 3f0 error, you need to perform one more step.

• Go back to the Command Prompt and type  bootsect /nt60 SYS .
• If this command doesn’t work, try  bootsect /nt60 ALL . If the hard disk 3F0 error reappears, move on to the next method.

Method 5: Reconnect Your Hard Drive

Reconnecting the hard drive may also help you fix Boot Device Not Found 3F0 error. Follow the steps given below:

• Turn off the computer.
• Remove the power cable and battery.
• Disconnect your hard drive and then connect it back.
• Reassemble your computer and turn it on to see if the error persists.
