I think you must have noticed these: 1. My boot USB is boot in EFI mode 2. My system is not currently a EFI boot environment. There is no EFI partition. 3. The installation fails because of (2).
Judging from (1), you can only be certain that my system COULD SUPPORT EFI. You cannot be certain that my system IS USING EFI to boot OS in my harddisk. And as you stated clearly: (a) The installer is judging to use grub-efi by (1) and only (1); But, (b) grub-efi CANNOT be installed under situation (2). (c) Situation (1) and situation (2) are not mutually exclusive. Now, contrary to the installer's logic, grub-efi can only be installed if my system if it IS USING EFI, not it COULD SUPPORT EFI. That means when the installer thinks it is OK to install grub-efi on my system, it is wrong. Right? I described this as "confusion". You might not like my word, but facts remain. Then you basically stated that it is a user's problem of not letting the installer to wipe the harddisk. If that's the case, perhaps it is a huge bug for the installer to pretend that user can choose otherwise. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1299134 Title: grub-installer failed during install trusty 64bit To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1299134/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
