42 is broken on my PC.
I get the following error at boot:
Error reading NLS file
The PC is an ASUS K53E I5 legacy BIOS with a built in DVD reader.
41 boots just fine.
The last build that works properly is 71365.
Build 71366 and all later builds HAVE THE PROBLEM on my PC.
I tried to look at the comments in your repository for that build
but it will not let me go back that far.
