[Bug 1912677] Re: autogenerated entries for other Ubuntu systems use wrong root filesystem, unbootable
Things are complicated, and they work fine if you don't use secureboot UEFI. Multiple ubuntu systems work fine in BIOS mode, but on UEFI grub-install only installs one "ubuntu" boot loader entry and hence if you run multiple ubuntus, you essentially flip back and forth between their grubs on /boot/efi which is suboptimal. I'm not sure if grub devs ever thought about users having two installs of one system. But it's hard to solve the problem of people changing disks and not indefinitely growing the number of boot loader entries with each new disk. Anyhow, yes, I guess it needs fixing, needs some digging into what's going on. Windows is a lot simpler, as that code just chainloads window's bootloader, and doesn't have to deal with setting up the other kernel entries :) ** Changed in: grub2 (Ubuntu) Importance: Low => Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1912677 Title: autogenerated entries for other Ubuntu systems use wrong root filesystem, unbootable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1912677/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Wow, really? But if multiple Linux partitions (common since the days of LILO) are discouraged now, why is os-prober searching for Linux distros on unmounted partitions and adding them to grub.cfg? If it's just for Windows and anything else isn't supported, maybe it should only add Windows installs. I don't mind adding grub stanzas by hand for distros on other partitions. But automatically added grub entries that are wrong and won't boot just clutter the boot menu, making it hard to tell which are the working entries. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1912677 Title: autogenerated entries for other Ubuntu systems use wrong root filesystem, unbootable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1912677/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Running two *Ubuntu installs on the same system is not really supported, as there can only be one grub installed. Same for os-prober really, it doesn't really work correctly for anything other than Windows. So I understand that there's an issue, and we can fix this, but the expectation is that os-prober will go away at some point, and you should not run two ubuntus on one system. Though I guess you can override the grub distributor is environment variable to hack around things, making the second Ubuntu install as like ubuntu2 to the ESP, and then select that from the UEFI boot device menu. ** Changed in: grub2 (Ubuntu) Importance: Undecided => Low ** Changed in: grub2 (Ubuntu) Status: New => Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1912677 Title: autogenerated entries for other Ubuntu systems use wrong root filesystem, unbootable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1912677/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
