Thanks for reporting. Have you tried using Boot-Repair to restore GRUB (the component that allows Ubuntu to boot and that gave you an error)? You can install and run it from an Ubuntu live CD (if you have got Internet access): boot your Ubuntu live CD, connect to the Internet, then follow the instructions at <https://help.ubuntu.com/community/Boot-Repair>, section "2nd option : install Boot-Repair in Ubuntu". After the main Boot-Repair window appears, click on "Recommended repair". If the repair does not succeed, the program will give you an URL; in that case, paste it here so that I'll be able to determine what caused the error.
Tell me if it works; in these days, I'll try to reproduce the problem myself to see if it is still present in the next release of Ubuntu and, if so, I'll tell the developers so that they can fix the bug. One last thing: you mentioned an antivirus software in your report. Do you also have Windows installed? If so, which antivirus software have you got? (Anyway, Windows antivirus software usually will not interfere with Ubuntu, nor will it run in it, because it's a completely different operating system). Thanks again for making Ubuntu better! ** Changed in: ubiquity (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/885983 Title: error: no such device: a6e9ac82-12c2-4c83-ac35-b7b29d8cc206 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/885983/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
