Discovered the same problem on Ubuntu 14.04 and 14.10. One of the worst thing is that a step of the installation (GRUB position in the "mount point" settings) is just broken and doesn't work properly with multi-boot systems. The last installed *buntu will be always set as the default system, even if you DON'T select /dev/sda for GRUB.
After every installation I have to use BootRepair to set the system that I wanted as the default one. Other wise I can leave everything as it is, with a secondary system set as default, but at every kernel update there's the need to run the secondary system to run the "update-grub" command... As this bug seems to be quite old, I'm afraid that probably there isn't an easy solution. Is there at least a easier/faster workaround? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1056101 Title: grub-efi overwrites an existing grub*.efi file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1056101/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
