I experienced this problem too on Ubuntu karmic installed via WUBI. Behaviour on my system is consistent with comment #47 by Mark Abene. I was able to boot my system using these commands on the grub shell:
sh:grub>linux /boot/vmlinuz-2.6.31-19-generic root=/dev/sda1 loop=/ubuntu/disks/root.disk ro sh:grub>initrd /boot/initrd.img-2.6.31-19-generic sh:grub>boot (2.6.31-20 gave the invalid magic number error) I installed the proposed lupin packaged on my semi-broken system, and now my system won't boot. It takes me to the grub shell like before, but the boot sequence ends with a weird Call Trace and a soft lockup (modprobe:683) after AppArmor profiles are loaded. -- After 9.10 grub update can not boot into Wubi install https://bugs.launchpad.net/bugs/477104 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
