What Does Boot Device Not Found Mean
What is a boot device not foundA "Bootable device not detected" issue occurs when your computer can't find a boot device, such as a hard drive or USB, to start up properly, resulting in an error message like "Boot Device Not Found. Please install an operating system on your hard disk 3f0."
When the problem occurs, you may see any of the following error messages on the screen:
- 'Boot device not found please install an operating system on your hard disk'
- 'No boot device found - insert boot disk and press any key'
- 'Boot device not found - hard disk (3f0)'
- 'No boot device is available
What Is the Cause of Boot Device Not Found
The "Boot device not found" error occurs when the system can't find a bootable device, such as an internal hard drive, external USB drive, optical CD/DVD ROM drive, or network adapter, to initiate the boot process. This indicates that the hard disk does not support the system boot process, and Windows OS is unable to find a device to boot from.
If the error message appears on your computer screen, it will no longer be able to start up normally. To resolve this issue, you should take immediate action to identify the cause of the missing bootable drive. This can be done by using the information provided in the following steps as a reference.
- The wrong boot order in the BIOS
- Hard disk connection problem
- System files or boot files unknowingly damaged
- The Master Boot Record (MBR) or boot sector is damaged on the bootable disk, preventing the operating system from loading and making it impossible to boot. This can be caused by a virus, a physical problem with the disk, or a software issue, and requires a repair or replacement of the MBR to resolve.
- Outside attacks can also come from third-party systems, such as applications, viruses, and malware, which can compromise a system's security.

To fix the "boot device not found" error, follow these recommended solutions. We offer both video and text tutorials to help you resolve the issue. With the factors mentioned in mind, start by attempting these steps to get your system up and running again.
1. Hard Reset Your Computer
A hard reset can re-The BIOS (Basic Input/Output System) is responsible for establishing a connection between the operating system and the hardware components of a computer. When a boot device not found 3F0 error occurs, it indicates that the BIOS is unable to locate a bootable device, such as a hard drive or solid-state drive.

- To safely power down your device, press and hold the power button for 15 seconds. This will completely drain the battery, ensuring a clean start.
- Press the power button to start the system. Select "Start Windows normally" from the "Startup" menu, then press Enter.
2. Reset Hard Drive to Fix No Boot Device Found Issue
Resetting the hard drive may fix the boot device not found error if the error occurs because of some loose connections.
- Press the Power button on your computer for a few seconds to shut it down completely.
- Unplug the power cord, then disconnect and reconnect the hard drive.
- To troubleshoot the issue, let's try reassembling the computer and restarting it to see if it works seamlessly. This will help us determine if the problem lies with the hardware or software.
3. Restore BIOS Default Settings and Modify PC Boot Order
To troubleshoot the issue of your computer not booting from a hard disk, you can try resetting the BIOS settings on your HP computer. This can be done by accessing the BIOS settings, navigating to the boot settings, and saving the changes. This process can help restore the default BIOS settings and potentially resolve the issue of the computer not booting from the hard disk.
- Press the Power button and repeatedly press the F10 key (or other manufacturer-specific key such as ESC, F1, F2, F8) to enter the BIOS setup menu.
- On the BIOS Setup screen, press F9 to load the default BIOS settings.
- Press F10 to Save and Exit.
- Select "Yes" using the arrow keys and press Enter when prompted to exit saving changes.
- Follow the prompts to restart your computer.
If resetting the boot order doesn't solve the problem, you can try using Bootrec.exe in the Windows RE to troubleshoot startup issues, and if that doesn't work, there are other solutions available.
4. Check Bad Sectors on the Bootable Hard Disk
Bad sectors on a hard drive can cause it to malfunction, leading to a "boot drive not found" error. These sectors are damaged due to physical wear and tear, making the drive unresponsive to read or write requests. To resolve this issue, it's essential to detect and repair bad sectors to restore the drive's functionality.
Qiling Partition Master can help you do a surface test for a bootable disk easily and quickly. To do this, you need to create a WinPE bootable disk first, then boot your computer from the disk to check and repair bad sectors.
To fix a non-bootable hard disk, boot from the WinPE disk and check if the hard disk is bootable. If not, you can try to fix it using a tool like EaseUS Partition Recovery to recover data from the unbootable hard disk. If the hard disk is bootable but the system won't boot, you may need to use a tool like Bootable Media Creator to create a bootable USB drive.
Step 1. Open Qiling Partition Master, click the disk you want to check, then click "Surface Test".
Step 2. The operation will be immediately performed and all bad sectors will be marked as red.
Bad sectors on a hard disk can be categorized into logical and physical types. Logical bad sectors can be resolved using CHKDSK /F or SFC command lines, but if there are numerous physical bad sectors, it may be necessary to replace the hard disk with a new one due to the potential for a boot device not found issue.
5. Fix and Rebuild Damaged MBR
The Master Boot Record (MBR) is the first sector of a hard disk or diskette that identifies the location of an operating system to be loaded into the computer's main storage or random access memory. A boot device not found error can occur if the MBR is damaged, which may be due to malware, disk failure, or MBR overwrite. In such cases, rebuilding the MBR can help resolve the issue.
Step 1. Create a WinPE bootable disk
- Launch Qiling Partition Master, click "Create bootable media" on the tools page, and select to create the bootable disk on a USB drive or CD/DVD.
- Click "Proceed" to finish the process.
Step 2. Boot Qiling Partition Master Bootable USB
- Connect the bootable USB or CD/DVD to your PC.
- To enter the BIOS screen, press F2 or Del when restarting the computer. Once in the BIOS, set the computer to boot from "Removable Devices" or "CD-ROM Drive". After this, Qiling Partition Master will automatically run.
Step 3. Rebuild MBR
- Click the disk whose MBR is damaged. Choose "Fix boot" to continue.
- Select the type of MBR with the current operating system.
- Click the "Proceed" to build the MBR. After that, your computer can boot normally again.
