** Attachment added: "grub.cfg"
https://bugs.launchpad.net/ubuntu/+source/lupin/+bug/738345/+attachment/1921266/+files/grub.cfg
** Description changed:
The 10_lupin script generates menu entries to boot Wubi installs. The
following entry has been created:
### BEGIN /etc/grub.d/10_lupin ###
menuentry "Ubuntu, Linux 2.6.38-7-generic" {
- insmod ext2
- set root='(/dev/loop0)'
- search --no-floppy --fs-uuid --set=root
23b0f259-6cdd-4cd2-bc50-8febbcb784b0
- loopback loop0 /ubuntu/disks/root.disk
- set root=(loop0)
- linux /boot/vmlinuz-2.6.38-7-generic root=UUID=80E4E195E4E18DAA
loop=/ubuntu/disks/root.disk ro quiet splash
- initrd /boot/initrd.img-2.6.38-7-generic
+ insmod ext2
+ set root='(/dev/loop0)'
+ search --no-floppy --fs-uuid --set=root 23b0f259-6cdd-4cd2-bc50-8febbcb784b0
+ loopback loop0 /ubuntu/disks/root.disk
+ set root=(loop0)
+ linux /boot/vmlinuz-2.6.38-7-generic root=UUID=80E4E195E4E18DAA
loop=/ubuntu/disks/root.disk ro quiet splash
+ initrd /boot/initrd.img-2.6.38-7-generic
}
The UUID 23bf... is the loop device /dev/loop0. The file
/ubuntu/disks/root.disk is not on the loop device, it's on the host
(UUID=80E4...). So to 1) set root to /dev/loop0 which it should be,
override to /dev/loop0 by uuid, and then try to loop mount
/ubuntu/disks/root.disk won't work.
+ I'm not sure exactly what the cause of the message is - but after selecting
to boot, the next screen you get a blank screen with:
+ "Error: file not found.
+ Press any key to continue"
+ After pressing a key it then boots normally.
+
+ This did not happen on the initial install, so I assume it's changed since
running updates.
+ I also noticed a flashed 'Error: file not found' just before the grub menu
displays. This also did not happen on the initial install.
+
+ Just for reference here is a copy of a Lucid version of a lupin
+ menuentry for Wubi. Note the differences of insmod ntfs, and setting
+ root to the partition (not loop device).
+
On a lucid wubi it looks similar to this:
### BEGIN /etc/grub.d/10_lupin ###
menuentry "Ubuntu, Linux 2.6.32-27-generic" {
- insmod ntfs
- set root='(hd0,1)'
- search --no-floppy --fs-uuid --set 80E4E195E4E18DAA
- loopback loop0 /ubuntu/disks/root.disk
- set root=(loop0)
- linux /boot/vmlinuz-2.6.32-27-generic root=/dev/sda1
loop=/ubuntu/disks/root.disk ro quiet splash
- initrd /boot/initrd.img-2.6.32-27-generic
+ insmod ntfs
+ set root='(hd0,2)'
+ search --no-floppy --fs-uuid --set 80E4E195E4E18DAA
+ loopback loop0 /ubuntu/disks/root.disk
+ set root=(loop0)
+ linux /boot/vmlinuz-2.6.32-27-generic root=/dev/sda2
loop=/ubuntu/disks/root.disk ro quiet splash
+ initrd /boot/initrd.img-2.6.32-27-generic
}
- I'm not sure exactly what the cause of the message is - but after selecting
to boot, the next screen you get a blank screen with:
- "Error: file not found.

- After pressing a key it then boots normally.
