New ISOs can only install in UEFI not Legacy Boot

I have been creating custom ISOs monthly. I changed nothing. All seems to build fine except some errors in the building process like:

(14/19) Updating Grub-Bootmenu
/usr/bin/grub-editenv: error: cannot open `//boot/grub/grubenv.new'
/usr/bin/grub-mkconfig: line 271: /boot/grub/grub.cfg.new: No such file or directory

I think I got these before. All goes well and installs the ISO but only when booting into UEFI mode. When booting into Legacy Boot it fails at around 98% install with such errors:

The bootloader could not be installed. The installation command <pre>grub-mkconfig -o /boot/grub/grub.cfg</pre> returned error code 1.

I reinstalled the manjaro tools git versions, I checked so many things...I simply cannot know what to do.

Used to work just fine. Now it only works to install in UEFI.

@Tio This should be fixed with recent versions of grub. Are you using the unstable or stable branch?

Great! I am using Stable but I guess it didn't land in Stable yet? I will test as soon as it does. Thanks!

That fix is backported to 25.0.10 of Manjaro OS already.

So that means I could give it a go and build a custom ISO with Manjaro's Tools already?
