Boot Device Not Found 3F0.

HP Recommended
Laptop 14S
Microsoft Windows 10 (32-bit)

Hi All,

I understand that to resolve "Boot Device Not Found 3F0" problem, just follow the steps below.. as provided by HP Customer Support. Thing is I cant find the Legacy Support in the BIOS. It is nowhere to be found!

 

  • Start or restart the computer.
  • Press F10 repeatedly during start up to enter the BIOS configuration utility.
  • Check Legacy Support and disable if it is enabled:

System Configuration > Boot Options > Legacy Support

or

Boot Options > legacy Support

  • If Legacy Support is DISABLED, skip to Procedure 3, Step 3. If Legacy Support is ENABLED, change it to DISABLED, save the changes and exit, then go to Procedure 3.

@KPH1 

You claim the laptop is running Win10.  If it came with Win10 preloaded, then it was preloaded in UEFI mode -- and forcing the BIOS to Legacy mode will ensure that it will no longer boot.

 

This issue is often due to a failing drive. So, let's check that first, because if it is failing, it would need to be replaced and there is no point then in doing anything else until we confirm that.

If your PC is new enough to support UEFI, you can use these steps to test the hard drive: http://support.hp.com/us-en/document/c00439024

If not, to check the drive you have to follow these steps:
1) Press Esc key repeatedly, several times a second, while rebooting the laptop. Do NOT hold the key down, just press it over and over.
2) Eventually, you will see an HP Startup Menu
3) Press the Function key for testing the hard drive (usually F2) and let it run.
If the drive checks out OK, then report that and I can provide you options for reinstalling Windows on your PC.
