Bug #1050590 is marked as duplicate of this bug. Are you sure this is the case? I see nothing here to indicate the following issue described in Bug #1050590:

["'grub-efi' package failed to install into /target/. Without the GRUB boot loader, the installed system will not boot."

This exact error occurs on a Lenovo B570 while attempting to install UBuntu 12.10 daily builds, hence the special documentation for installing Ubuntu on Lenovo B570s with instructions for overriding grub-efi with 64-bit installations in order to boot after installation (the B570 uses MBR, not GPT) no longer works, since grub-efi-amd64 will not even install in the first place, for whatever reason.

This really ought to be dealt with before release. It's a show-stopping bug for affected hardware (at least some ASUS and Lenovo).]
