BOOT DEVICE NOT FOUND

[Rafy0322]

I tried to change my bios legacy and everything but it still says no boot device found. When I try to run a check test or a exclusive test, it says not installed. I’m pretty sure that means I need to buy a new hard drive for my laptop. Does anyone know where I could order one? I need my laptop for school and I don’t want to send it to bestbuy so they could just hold it for weeks

First off, most new laptops that come with Win10 preloaded come configured in UEFI mode.  If you change that to Legacy or CSM mode, Windows will no longer boot. So, forcing a mode change will not fix the problem.

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.
