I have a blue recovery screen on a HP All-in-One - 24-g063a with error cod Oxc0000034.

Blue Screen 

RECOVERY

Your pc/device needs to be repaired.

The boot configuration data for your PC is missing or contains errors.

File:\EFI\Microsoft\Boot\BCD

Error code: 0xc0000034

You'll need to use recovery tools. If you don't have any installation media (like a disc or use device), contact your PC administrator or PC/Device manufacturer.

Flashes to black HP screen after 20 to 30 seconds and says Keyboard error.

Windows will not load.  Have tried all tips and tricks

In its current state, it is never going to load -- because the BCD is corrupted.

You will need to create Boot Repair Media using a working PC.

Macrium Reflect is a free tool that can be used to image and restore PCs, but it also has an option to create Rescue Media (in disk or USB form) that can then be used to boot and/or Repair your PC.

It is available from here: http://www.macrium.com/reflectfree.aspx

What I recommend is the following:
a) Download and install Macrium Reflect (MR)
b) Use the option to create a boot USB stick or CD
c) Boot your PC from the MR media -- it will take a while, so be patient!
d) If needed, select the option to repair the Windows Boot

The PC should now reboot without problems. IF it still has problems, there are other issues at play.

These steps didn't resolve my issue.
