My uncle left this HP Stream 7 tablets at our house, saying we could have it if we could fix it. Whenever it's turned on, it goes to this blue screen that reads:
Recovery
Your PC\Device needs to be repaired
The application or operating system couldn't be loaded because a required file is missing or contains errors
File : \$Windows.BT\NewOS\WINDOWS\system32\winload.efi
Error Code: 0xc000000f
You'll need to use the recovery tools on your installation media. If you don't have any installation media (like a disc or USB deivce), contact your administrator or PC manufacturer.
Press the Windows key to use a different operating system
but, nothing happens when you push the windows button on the bottom. I've tried Googling the problem already, but I can't seem to find anyone who's having a similar problem. I don't know anything about it aside from what kind of tablet it is.
