Yes.=C2=A0 I did not upgrade the test VM directly.=C2=A0 I replaced GRUB 2.= 00 with 2.02 in my build automation which creates an installer ISO.=C2=A0 I= nstallation onto the VM is also largely automated.=C2=A0 GRUB 2.02 (and 2.0= 0) work fine if I revert the config file to that in 1.42.13.
Do you mean grub is unable to read some files ? Can you try, r= ecreating it with grub-fstest? Can you upload failing image somewhere?

To be clear:=C2=A0 I don=E2=80=99t believe any of the code changes between = 1.42.13 and 1.43.4 cause this issue.=C2=A0 The problem arises from just the= changes in the built-in default configuration file that gets installed.=C2= =A0 A distro that uses its own custom configuration file may not encounter = this issue.

Yes, my test VM is configured to chain load GRUB from Syslinux (ISOLINUX).= =C2=A0 I don=E2=80=99t recall whether I tried booting directly into GRUB so= I will test that tomorrow.
