Comment 14 for bug 1043149

My previous post was after "Restarting" the computer from Windows 8 and booting into Wubi. The next test was to "Shut down" from Windows 8 and boot Wubi. That also worked, but I've observed a different behaviour when booting Wubi from Windows 8 manager as compared to Win 7 and that is:
1. Computer starts, BIOS screen
2. Windows boot manager, select Ubuntu(Wubi)
3. Computer restarts, BIOS reappears, boots directly into Ubuntu(Wubi)

So it appears that Windows is taking care of the 'fast-start' hibernated image from the Windows Boot Manager when required. (Of course when it's really hibernated it just boots straight into Windows)

It's different when I shut down Windows 8 and then boot the non-Wubi install (12.04.1). Then when I try to mount the windows partition I get:
bcbc@neptune:~$ sudo mount /dev/sda1 /mnt
Windows is hibernated, refused to mount.
Failed to mount '/dev/sda1': Operation not permitted
bcbc@neptune:~$ sudo mount -r /dev/sda1 /mnt
bcbc@neptune:~$ head -c 8 /mnt/hiberfil.sys | od -t x1
