Yes.  I did not upgrade the test VM directly.  I replaced GRUB 2.00 with 2.02 in my build automation which creates an installer ISO.  Installation onto the VM is also largely automated.  GRUB 2.02 (and 2.00) 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, recreating it with grub-fstest? Can you upload failing image somewhere?

To be clear:  I don’t believe any of the code changes between 1.42.13 and 1.43.4 cause this issue.  The problem arises from just the changes in the built-in default configuration file that gets installed.  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).  I don’t recall whether I tried booting directly into GRUB so I will test that tomorrow.
