1. Enter the BIOS with F1 2. Go to the Startup Tab 3. Disable SecureBoot 4. Enable CSM 5. Set boot priority to Legacy 6. Save, reboot and reinstall Ubuntu -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1302939 Title: Installing Ubuntu 14.04 on Lenovo H520 leads to unbootable system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1302939/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
