[SOLVED. Bug?] Re: How to specify EFI System Partition's mount point in ubu installer?

[PGNet Dev]

The boot-to-UEFI fail issue's due to a missing 'startup.nsh'.

It does not appear that it's created during the install process.

The fix is straightforward, if not quite enduser-friendly.

After installer stage is complete, destroy, do not reboot, the Guest.

@ Dom0 host's shell, mount/edit the EFI partition

	kpartx -av /dev/VG0/part_EFI
	mount /dev/mapper/VG0-part_EFI1 /mnt
	echo "\EFI\ubuntu\grubx64.efi" > /mnt/startup.nsh
	umount /mnt
	kpartx -dv /dev/VG0/part_EFI

then reboot.  Guest boots successfully to EFI as intended.

In my book, an installer bug.  But I don't know if that's by design @Ubuntu.
