Do you have a buddy over there that could get you a copy of the bcdedit screen like you posted. Since I am not familiar with what it needs to be, it would be good to compare them.
I thought the command would replace your current bcd store, but maybe not. I suppose I need to do some more experimentation.
Anyway, where we need to go is to remove one of the BCD entries and possibly alter the other one.
After the last attempt, did you check the bcdedit readout to see what changed?
You might try another bcdboot command attempt, this time we can add the language switch.
bcdboot C:\Windows /l nl-NL
