Same issue as posted in #3 with new 18.04. Install to flash drive, does not use ESP on flash drive, but installs to ESP on sda. Then system is not bootable without flash drive as it has overwritten my default boot on sda from /EFI/ubuntu.
I also have changed GRUB_DISTRIBUTOR as defined in /etc/default/grub to have unique UEFI and grub menu entries for my internal drive system. Even though grub-install creates new /EFI/bionic_18_04 folder and entry in UEFI. And EFI folder had correct grub.cfg, the system only booted from grub.cfg in /EFI/ubuntu, Or something in grubx64.efi is hard coded to only boot from /EFI/ubuntu/grub.cfg. Better to fix grub not use use hard coded efi_distributor as ubuntu and fix kluge of kubuntu name change. ./debian/patches/install_efi_ubuntu_flavours.patch:Subject: Cope with Kubuntu setting GRUB_DISTRIBUTOR ./debian/patches/install_efi_ubuntu_flavours.patch:we probably need to split GRUB_DISTRIBUTOR into a couple of different -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1229488 Title: EFI install to removable media not supported To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1229488/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
