My computer won’t boot windows

[BTDubs88]

When ever I turn on the computer It gets stuck on a screen That says “Boot device not found

please install an operating system on your hard disk

hard disk 3F0

and the diagnostic tests does not do anything the memory test runs but the storage test says there is no storage installed. I’m not sure what went wrong it ran perfect last night.

Ordinarily, when a laptop no longer boots into Windows, this means that the boot records (known as the BCD) have become corrupted due to a failing drive and running diagnostics confirms this to be the case. Folks then replace the laptop drive, use the HP Cloud Recovery option and a 32GB USB stick to make recovery media, boot their laptop from that media and do a full restore.

With a Stream, this is a much more difficult situation.

First, the Stream does not actually have a laptop hard drive. Instead, it has a memory stick configured to work like a "disk drive" -- so, it has an SSD instead of an HDD. This is very small, usually 32GB, so it is too small to do any major Windows Updates since Windows takes up nearly all of the "drive".

Second, the SSD, unlike the SATA SSDs in other laptops, can not be replaced by the consumer. So, when it fills up, you can't replace it with a larger one. And when it fails, you can't replace it with a new one.

Thus, you can try running diagnostics to test the drive -- but if it fails, you will have to take the Stream to a laptop repair facility to have them replace the SSD.

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.
