Windows 10: realtek sd card reader code 48

I have an HP Laptop with a Realtek PCIE Card reader. It stopped working after the Win 10 anniversary upgrade. It has the following device status on Device Manager;

The software for this device has been blocked from starting because it is known to have a problem with Windows. Contact the hardware vendor for a new driver (Code 48).

I have been to hardware vendor and did the update still not working.

Realtek USB 2.0 Card Reader


I've just upgraded to Windows 10 on my Dell laptop and I've been having problems with the Realtek card reader - see Realtek Card Reader Keeps Disappearing . You might find some tips in that link.

My card reader is listed under memory devices in Device Manager.

 

Boot from SD card Reader?


It likely depends on what the BIOS thinks the device is? If it shows up like a USB thumb drive it should work. If it requires drivers to even be detected it won't.
I know I wish I could boot from the built in SD Card reader in my laptop but the BIOS does not even see it. It's not listed as a boot option even with a bootable SD card in it.
