(Get the code!)
This happened to me too. There are two problems:
1) it defaults to installing grub on hd0 even if you are installing ubuntu to a different drive.
2) it doesn't say anything about it in the summary list, so you don't know you need to click the advanced button to change it.
These are, properly speaking, not grub problems but installer problems and is not new to grub2 but has been happening
at least as far back as feisty when installing to external drives.
The grub part of the bug is that it writes the mbr onto one drive with the first part of the loader which then expects to load the
rest from another drive. If the former is the internal disk and the latter is an external (and therefore not necessarily available)
disk, this is a recipe for disaster.
I think grub should refuse to write the mbr on a drive which doesn't have the rest of it.
