I have xubuntu 9.10 installed with wubi. After regular kernel update (2.6.31-15) grub fail booting default kernel with message "load kernel first". I still can boot system using record for 2.6.31-14 in grub. Grub boot sequence for 2.6.31-14 and 2.6.31.15 are identical (see attachment).
Wubi installs linux into hdd image file which is placed on standard windows filesystem (in my case, ntfs). So linux is booted with loop option (maybe this is the key). I reproduce all booting steps with grub command line and everything is ok until I run linux /boot/vmlinuz-2.6.31-15-generic root=/dev/sda5 loop=/ubuntu/disks/root.disk ro which shows me "error: invalid magic number" and fails boot. ** Attachment added: "Grub2 config file" http://launchpadlibrarian.net/37006737/grub.cfg -- Ubuntu Server 9.10 (karmic): grub2: error: invalid magic number https://bugs.launchpad.net/bugs/487689 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
