Repeatable on dual-boot. The expected behaviour for dual-boot is that the grub menu will show.
Whatever process detects dual-boot during reconfiguration of grub is failing as of 20.04.1 grub-mkconfig ?? This also occurs when using boot-repair, if boot-repair performs a reinstall of grub, then the new config follows the single boot convention and /etc/default/grub option is changed to: GRUB_TIMEOUT_STYLE=hidden To solve, manually change this addition back to default GRUB2 setting of: GRUB_TIMEOUT_STYLE= which defaults to show, or set explicitly using GRUB_TIMEOUT_STYLE=menu then update-grub This was mentioned in post #23. Adding this comment to show it's repeatable. If you re-install grub2, then a dual-boot is not recognised. @Julian Please re-assess. Your comments match only a single boot install. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1863434 Title: 20.04 grub menu not visible To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1863434/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
