Malbo has made further tests ( http://forum.ubuntu-fr.org/viewtopic.php?pid=10544711#p10544711 ), and it appears that:
- the bug is not present in 11.04 and 11.10, it has appeared in 12.04
- the bug is due to the fact that Wubi 12.04 can't mount the Windows partition.
**********
Output of "sudo mount -t ntfs-3g /dev/sdb1 /media/WindowsPartition" :
1) In 11.04 and 11.10: no error
2) In 12.04:
Windows is hibernated, refused to mount.
Failed to mount '/dev/sdb1': Opération non permise
The NTFS partition is hibernated. Please resume and shutdown Windows
properly, or mount the volume read-only with the 'ro' mount option, or
mount the volume read-write with the 'remove_hiberfile' mount option.
For example type on the command line:
mount -t ntfs-3g -o remove_hiberfile /dev/sdb1 /media/WindowsPartition
**********
After installing Wubi 12.04 into Windows8, and rebooting. When Ubuntu boot fails, a GRUB shell is prompted.
In this shell, Malbo typed:
mkdir /host
mount -t ntfs-3g -o remove_hiberfile /dev/sdb1 /host #Removes the hiberfil.sys file, and successfully mounts the Windows partition
exit
This allows to boot Ubuntu.
