If the nvram device is non-functional, e.g. because the nvram module isn't
loaded and it's file been removed from the filesystem, thus can't be
loaded, the installation will be attempted but the system will be left in
an unbootable state.
The boot process shows:
Welcome to GRUB!
error: ../../grub-core/kern/dl.c:380:symbol `grub_disk_get_size' not found.
Entering rescue mode...
grub rescue>
Introduce a point of no return after embedding grub in the PReP
partition, and make sure /dev/nvram is functional or fail early.
