I just installed the 12.04 beta 2 x64 on a PC that already has Win7 x64
EFI booting. When booting, the Grub menu is not show, as is standard, if
there are no other OS'es to select. Manually running an update-grub does
not detect Windows.

The /boot/efi/EFI/ folder containts 'Boot', 'Microsoft', and 'ubuntu'
entries. Both the Boot and ubuntu folders has .efi files in them, the
Microsoft folder, however, has a 'Boot' folder, that containts a whole
bunch of file (among them, some .efi files).
