Comment 7 for bug 1229886

I can boot Windows from Grub, hibernate it, and then try to resume Windows from Grub. The error results.

I will have to test hibernating Windows, running Ubuntu, the trying to bring Windows out of hibernation. Not certain I tried that, but the issue of being unable to go right back to Windows suggests the Windows boot loader is unhappy with being called by Grub for hibernation resumption. Perhaps Windows looks for some data that Grub affects - I do not have technical info on the resumption from hibernation process.

Will also post my output of sudo parted -l when I'm at the machine.
