@ Norbert (nrbrtx) to overcome this bug, until some sort of fix is applied by the developers:
while logged into Jammy Jellyfish navigate to /etc/default/grub and add the following line and save: GRUB_DISABLE_OS_PROBER=false After the edit, in the console, run: sudo update-grub The grub menu will be set up and other operating systems on the device will be displayed next time the system starts. (Unfortunately this is viewed as a security problem, which has yet to be addressed.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1955109 Title: boot menu not appearing after manual install of jellyfish daily build alongside other OS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1955109/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
