Installed 19.04 to sdb drive (internal, but also flash drive as sdc) and it overwrote my /EFI/ubuntu folder on sda.
I changed combo box which never has done anything with UEFI installs, but it does then say during install that it is installing grub to sdb/external. I clicked on ESP on sda, and said do not use. I clicked on ESP on sdb and said use as ESP. Several years ago I installed Fedora, just to see grub differences, and it just installed to sdb when I told it to. So it is Ubuntu's modifications to grub that make it not install to drive you really want. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1396379 Title: installer uses first EFI system partition found even when directed otherwise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1396379/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
