Thanks for the follow up. You're right about the dual BIOS/UEFI
systems, so my suggestion wouldn't work. However we still have a problem
that grub setup generated a menu that results in :
GRUB loading.
Welcome to GRUB
There is no way to get a menu or anything in that context. Required a
rescue DVD boot.
That's what was meant by stalled.
Here's the grub.cfg it generates while /etc/grub.d/30_uefi-firmware is
executable:
#
# DO NOT EDIT THIS FILE
#
# It is automatically generated by grub-mkconfig using templates
# from /etc/grub.d and settings from /etc/default/grub
#
### BEGIN /etc/grub.d/00_header ###
