** Description changed: 64bits EFI computer (with GPT disk) with pre-installed 64bits Windows7. + AND 32bits EFI computer without legacy boot support 1) Installing Ubuntu 12.04 64bit creates a valid /efi/ubuntu/grubx64.efi entry. At reboot, the GRUB menu appears and allows to boot Ubuntu. 2) Installing Ubuntu 12.04 32bits installs grub-pc, which creates no EFI entry. Ubuntu can't be booted (except if it is possible to deactivate EFI mode). 3) Installing grub-efi from an already installed Ubuntu32 creates /efi/ubuntu/boot.efi , and /efi/ubuntu/grubia32.efi . Both EFI entries fail. 4) Installing grub-efi in an already installed Ubuntu32 in chroot via an Ubuntu64 live-CD ( so that grub-efi has access to EFI variables) also creates two invalid EFI entries (/efi/ubuntu/boot.efi , and /efi/ubuntu/grubia32.efi ). - CONCLUSION: - grub-efi 32bits always creates invalid entries. - Installing Ubuntu32 bits on an EFI system should be blocked by Ubiquity (the Ubuntu installer). In this case, Ubiquity should ask the user to install Ubuntu64 instead. - the Download page should warn that the 32bits ISO is not compatible with recent (EFI) computers
