I just experienced this issue on my primary box. Outlined here - https://discourse.lubuntu.me/t/lubuntu-jammy-issue- tracker-os-prober-grub-2-06/2952/3
- dell [optiplex] 960 (c2q-q9400, 8gb, amd/ati cedar radeon hd 5000/6000/7350/8350) Each ~fortnight I reboot from my usual *jammy* into my backup dualboot system (*focal*) to update it's packages etc.. but earlier today on reboot no grub menu appeared & I found myself back in jammy. The grub entries were only for the jammy system. It'd been 16 days since last reboot on the box. -- 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1955109/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
