Having discussed the reasons behind the occurrence of the “Boot Device Not Found 3F0” error, we will now delve into the methods for resolving this issue.

Methods To Fix Boot Device Not Found 3F0 Error

Follow the methods given below to fix the boot device not found 3F0 error.

Method 1: Change The Boot Order

Ensure that the hard drive you boot from is the right disk. If you set to boot from an unbootable device, it won’t boot and may display the error message: “Boot Device Not Found. Please install an operating system to your hard disk”. In such a situation, you can change the boot order in BIOS and let it boot from the bootable device. To do so, follow the below-given steps:

• Restart the computer and then press the F10 key to enter the BIOS settings menu.
• After opening the BIOS, go to the boot settings.

1. Notebook computers: Select Storage > Boot Options.
2. 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 below-listed steps:

• Turn off the computer and remove it from any port replicator or docking station.
• Then, 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, select Start Windows Normally with arrow keys and press Enter.

Method 3: Restore BIOS To Default Settings

It may happen that your system is configured to boot from an unbootable disk. In such a case, resetting your BIOS restores it to the last saved configuration. 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 Exit Saving Changes.
• Then, follow the prompt to restart the computer.

If the computer restarts normally, it means that 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 any issue, you may encounter the ‘Boot device not found 3F0 error’. You can fix it by following the below-given steps:

• Press F8 while booting and check if you can get to Windows Recovery. If yes, go to Advanced > Command Prompt. If you couldn’t, you’ll need a bootable ISO.
• In the Command Prompt Window, enter the following commands:

1. bootrec /RebuildBcd
2. bootrec /fixMbr
3. bootrec /fixboot

• Now reboot and check for the error status.

If the above steps didn’t fix the error, you need to perform one more step. Go back to the Command Prompt and type in bootsect /nt60 SYS or bootsect /nt60 ALL. If the first command doesn’t work, then try the other one.

Method 5: Reconnect Your Hard Drive

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

• Turn off the computer.
• Remove the power cable and battery.
• Disconnect your hard drive and then connect it back.
