Comment 5 for bug 487689

I have the same symptoms as Nick in comment #4.

I installed Ubuntu 9.10 using Wubi, and then upgraded to Lucid. When I try to boot the Lucid kernel, I get the "Must load kernel first" and then when I disable "screen" I also see the "invalid magic number" error. I am running the amd64 architecture packages on a machine with a SU7300 Intel processor.

This entry works:

menuentry "Ubuntu, Linux 2.6.31-18-generic" {
 insmod ntfs
 set root=(hd0,2)
 search --no-floppy --fs-uuid --set bc1235091234ca62
 loopback loop0 /ubuntu/disks/root.disk
 set root=(loop0)
 linux /boot/vmlinuz-2.6.31-18-generic root=/dev/sda2 loop=/ubuntu/disks/root.disk ro
 initrd /boot/initrd.img-2.6.31-18-generic
}

/dev/sda2 on /host type fuseblk (rw,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other,blksize=4096)
/dev/loop0 on / type ext4 (rw,errors=remount-ro)

This one fails:

menuentry "Ubuntu, Linux 2.6.32-11-generic" {
 insmod ntfs
 set root=(hd0,2)
 search --no-floppy --fs-uuid --set bc1235091234ca62
 loopback loop0 /ubuntu/disks/root.disk
 set root=(loop0)
 linux /boot/vmlinuz-2.6.32-11-generic root=/dev/sda2 loop=/ubuntu/disks/root.disk ro
 initrd /boot/initrd.img-2.6.32-11-generic
}
