Windows 10 wont boot after AVG update

When the PC boots it comes up with a screen saying "Starting watch Dog Initialization". I have discovered this is related to AVG. I have followed the instructions on a AVG forum about disabling AVG by using a bootable CD to access the file system. Then I renamed all the files beginning with AVG in c:\windows\systems32\drivers folder - adding .old to the end of the files. This is all as per the AVG instructions.

Now when I try to boot the system it stops with a Error : 0xc000000f saying that the avgboota.sys file is missing.

How do I resolve this?

It seems that AVG has entries in the Boot order to fix this you have to boot with your Windows installation media and perform a repair your computer
Select your installation ..then next and select in the recovery options --> Command Prompt.
type bootrec and then type the following commands
bcdedit /export C:\BCD_Backup
    cd boot
    attrib bcd -s -h -r
    ren c:\boot\bcd bcd.old
    bootrec /RebuildBcd
