I had the "Error 15" message after upgrading to 9.10. In my configuration, the boot dir has its own partition. The grub config expect the kernel and the initramdisk to be loaded from /boot/vmlinuz-2.6.31-14-generic and /boot/initrd.img-2.6.31-14-generic.
However those files are located in the root of the boot-partition. adding a link from . to boot in the root of the boot partition solved the problem as in: $ ln -s . boot this seems to be a standard configuration for grub, when looking at other distros. I am still using grub 1 -- Upgrade 8.10 to 9.04 Grub Error 15 on reboot https://bugs.launchpad.net/bugs/366556 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
