I have managed to reproduce it, I have update grub clearly adding a Windows 10, but the timeout adjustment code isn't added to grub.cfg...
EDIT: hmm so it seems because /etc/grub.d/30_os-prober doesn't set find_other_os=1 for the BIOS chainboot case. It does seem to work for EFI versions of windows and that's why this wasn't caught. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2080785 Title: Wrong defaults after (deprecated) changes: #GRUB_TIMEOUT_STYLE To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/2080785/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
