Good afternoon. I recently bought a laptop "HP 250 G6" brand new. When i booted it it was okey. After 3 hours when i tried to open it, it said "boot device not found". I called HP support and they said to run a hard disk diagnostic. I did it and it said that there is no hard drive inside. I sent it back to them to send me a new laptop "DOA" but they said that they also have to see the problem and then they are gonna send me a new one. They sent me an e-mail saying that their diagnostic didn't find the problem and that the hard drive is ok. Do you have an idea of what could have happen?
