I have a dual boot computer with Ubuntu 14.04 LTS and Windows 8.1. My Ubuntu has recently started notifying me about the 16.04 Xenial Xerus update with an Upgrade option. If I upgrade, will the dual boot remain alright without affecting the GRUB console? Has anyone tried it out?

    So long as the upgrade goes correctly, you will be okay.

  • @Zalgo, have you tried this out on a dual boot computer? Aug 2, 2016 at 20:59
  • yes, my main setup is a dual boot with 16.04 and windows 10, for when i cant run something through wine. EDIT: if something does go wrong, running the update-grub command should fix it anyway.

  • My upgrade with similar dual boot went without any problems. I think GRUB is updated after every new kernel update, which you should have had plenty if you did regular updates in the past.

  • @Valentas, is the Windows partition unaffected? Aug 5, 2016 at 8:01

A fresh new install is better and safer than an upgrade.


Cleaning the system with bleachbit and ubuntu-tweak and rebooting it before upgrading has always been a safe way for me.
