leapp from OEL 7.9 to 8 fails to grub rescue

I have tried leapp on a system numerous times and have tried everything I can think of to covert it from OEL 7.9 to OEL 8 but after the upgrade, it keeps rebooting into grub rescue.

ls (hd0,msdos1)/grub2 has the grub files

ls (hd0,msdos1)/ has the kernels

I can change root= from hd0,msdos1 to (hd0,msdos1)

"isnmod normal" replies with "error: symbol 'grub_real_boot_time' not found.

I successfully converted the VM from grub to grub2 and confirmed with numerous reboots before the leapp upgrade.

Thanks for any help in advance. I have been struggling with this process for about a month. I had no problem using leapp to covert two VMs from OEL 8 to 9, This is the first OEL 7 to 8 I have been testing.
