Boot Device Not Found error

[SCG04]

HP Stream Laptop 

Model 14-cb163wm

ProdID 6SHO6UA#ABA

Warranty 1y1y0y

Purchased new in August 2019

Was in the middle of a school project on google docs and the laptop blinked and code flashed on the screen for a second and then the following error message appeared:

Boot Device Not Found

Please install an operating system on your hard disk.

Hard Disk (3F0)

F2 System Diagnostics

For more information, please visit: www.hp.com/go/tech center/startup

i have turned the computer off to restart and the same message appears.  I have  done F2 diagnostics with no help.  I have done F10 to look at boot options- everything appears to be as it should be.  I need to get the laptop back up to recover the papers I am working for my online class.  Can anyone give me suggestions?

@SCG04 If you've gone through this HP article - Boot Device Not Found Error or Hard Drive Not Detected and yet the issue persists, here's what you need to know & do:

After investigating the issue and looking at various user reports, we have created a list will culprits that are often responsible for causing the selected boot device failed error:

• Secure Boot is enabled in BIOS – The error is often reported to occur when secure boot is enabled and legacy mode is deactivated.
• Legacy boot is disabled in BIOS – Certain computers (especially older HP and Dell models) will display this issue when Legacy Support is disabled from the BIOS settings menu.
• Hard disk failure – This particular issue can also occur if your hard drive has developed bad sectors that prevent your operating system from being loaded.
• System file corruption – Corrupted Windows system files can also lead to the apparition of this issue.

Method 1: Disabling Secure Boot and Enabling Legacy BOot from BIOS settings

Users in a similar situation have reported that the issue was fixed and their computer booted normally after they accessed the BIOS settings and disabled Secure Boot. Other users have reported that the issue was only fixed after they enabled Legacy Support.

You can verify if this fix is effective by accessing your BIOS during the startup phase. To do this, press the Boot key (F10) during the startup process,

Once you’re into your BIOS settings, look through the System Configuration options and find Legacy Support and Secure Boot.

Once you do, set Legacy Support to Enabled and Secure Boot to Disabled. Then, make sure to save this configuration and reboot your computer.

Method 2: Reinstalling windows to fix system file corruption, if you don't have a recovery media, you can use another computer and order it here or obtain a copy from cloud using this link: click here, and use this link for steps to reinstall the OS with the factory shipped OS.
