HP Stream has a Boot device not found meassage

[Bmep3]

I just purchased a HP Stream from a co-worker.  They erased the hard drive before giving it to me.  Now when I turn it on I get a

BOOT DEVICE NOT FOUND

PLEASE INSTALL AN OPERATING SYSTEM ON YOUR HARD DISK.

Hard disk (3F0)

any ideas????

also, when I hit F11 to erase the computer again nothing happens.  I have also tried to run a storage test but it doesn’t do anything either.

Since they erased the hdd that included the Windows 10 operating system. You will have to boot with a USB flash drive to reinstall Windows. You will need another working machine to create the flash drive.

Your Windows 10 license key is embedded in BIOS and you can reinstall Windows freely. Microsoft provides the free Media Creation Tool to download files and create a Windows 10 usb flash drive.You will have latest updated version of Windows 10. At least 8gb flash drive required:

Select Download tool now,save it,then Run.
If you agree to the license terms, select Accept.
On the What do you want to do? page, select Create installation media for another PC, and then select Next.
Select the language, edition, and architecture (64-bit or 32-bit) for Windows 10.
The Guide here shows the steps.Pay attention to Step 5 since you will be using another pc:

-------------------------------
When the flash drive is prepared insert it in a usb port. Power on the laptop and immediately start tapping Esc key. From the menu tap F9 key and use the arrow keys to move to and select USB. Tap Enter key.
When installing it should pickup the key from BIOS but if it asks at any point just choose "I don't have a key". It will continue and should activate once you are online.

This will not include the original software or drivers from HP but most of it can be installed from your Support page.
