How to fix the "Boot Device Not Found" error in HP

If your HP device is experiencing a "boot device not found" error, it's likely due to a faulty or improperly configured boot order, a failing or dead hard drive, or a corrupted boot sector. To resolve this issue, you can try resetting the boot order in the BIOS settings, checking and replacing the hard drive if necessary, or running a disk check and repair on the affected drive.

• Method 1. Change boot order
• Method 2. Perform a hard reset
• Method 3. Restore BIOS default settings
• Method 4. Check hard drive

▶ Method 1. Change boot order

To resolve the "Boot Device Not Found" error, ensure that the hard drive you're booting from is the correct disk, as booting from an unbootable device can result in this error message. If you've mistakenly set to boot from an incorrect device, you'll need to change the boot order in your BIOS settings to the correct drive. This can usually be done by entering your BIOS settings during startup, selecting the correct drive, and saving the changes.

To resolve the issue, install an operating system to your hard disk. Then, access the BIOS settings and change the boot order to prioritize the bootable device. If the device is already set as the primary boot device and you're encountering this error, try the following methods.

▶ Method 2. Perform a hard reset

To perform a hard reset, turn off your computer and unplug it from the power source. Press the power button for 30 seconds to discharge any residual power. Then, plug the power cord back in and press the power button again to turn it on. This process can help resolve issues like the no boot device is detected error.

Step 1. Turn off the computer. Remove the computer from any port replicator or docking station.

Step 2. Unplug the AC adapter from the computer and disconnect all external devices.

Step 3. Remove the battery from the battery compartment.

Step 4. Press and hold down the Power button for about 15 seconds to drain any residual electrical charge from the capacitors that protect the memory.

Step 5. Insert the battery, plug the AC adapter back into the computer, and leave all peripheral devices disconnected.

Step 6. Turn on the computer. If a start menu opens, select Start Windows Normally with arrow keys and press Enter.

If the previous method didn't work, you can try booting your computer from a USB drive or CD/DVD that contains your operating system. This is often referred to as a "bootable drive" or "live CD.

▶ Method 3. Restore BIOS default settings

To resolve the "boot device not found" error on an HP laptop, you can try restoring the BIOS to its default settings, which may resolve the issue. This can be done by accessing the BIOS settings, navigating to the "Advanced" or "Boot" tab, and looking for an option to reset the BIOS to its default settings, or by pressing a key such as F9 or F10 during boot-up to access the BIOS settings and reset them to default.

Step 1. Turn off the computer and wait at least five seconds.

Step 2. To access the BIOS setup menu, restart the computer and repeatedly press the F10 key. This will allow you to enter the BIOS settings and make any necessary changes.

Step 3. On the BIOS setup screen, press F9 to load the default BIOS settings.

Step 4. Press F10 to Save and Exit.

Step 5. Select Yes, then press Enter when asked Exit Saving Changes?

Step 6. Follow the prompt to restart the computer.

If the computer restarts normally, you're done. If it still displays the "boot device not found" error message, proceed to the next method.
