No bootable device found

[HazzoMorg]

My Computer had recently ran slow so I had reset it, I left it for a while came back forgot to put it on charge I booted it back up and then windows was gone and it lead me to that message. I’ve tried different computers to boot into with a usb with windows 10 on and it seems to work fine out when I do my laptop I just have no bootable device found 

I have a 

HP 255 G3 Notebook PC

<Sigh>  Every time I read one of these Factory-Reset issues posts I cringe and continue to wonder why everyone seems to think a factory reset is a miracle cure when, in many cases, it only serves to make things worse!

If the PC is really SLOW, a factory reset will do NOTHING to fix that, and will most likely fail -- leaving you with an unusable PC. If a factory rest starts out OK and then halts part way through, that is nearly always an indication of a failing drive -- which is a hardware issue that a factory reset will do nothing to fix.

To check for hard drive failing, 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, 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.

I’ve done everything that I could but there is no operating system detected the hard drive is completely wiped after a complete reset went wrong, My laptop refuses to boot from usbs

I really wish folks would quit saying "wiped" when, almost certainly, that is NOT the case!  Wiping a drive takes special software, which I am sure you did not run, as it also requires special boot media, which I am sure you did not create -- or you would have mentioned these in your thread.

Did you run the diagnostics I suggested to check the drive? If so, what did they report?

I did all the steps you asked me to do and it reported that nothing was wrong. And it wants mr to install an Operating System
