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.
- 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 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.
