Recently I installed Ubuntu 12.04.1 LTS on my Lenovo Y480. Hibernation was working properly after the Ubuntu install, but I was making sure all of the operating systems on my system worked, including OneKey Recovery (recovery partition). It is of note that I installed Windows 7 from scratch with a disk image I downloaded off of my university's DreamSpark program, and further to that I had to image the partition with Paragon Backup & Recovery, repartition to convert the Windows partition to extended, install Ubuntu, and then restore the image. During that process I also used the Windows disc to edit the BCD as to reuse the existing entry for the restored partition. I also used the automated "repair your computer" option.
With verification, I noticed that the "repair your computer" option actually wrote to the wrong BCD (the recovery partition), and I mounted the partition and restored the original BCD (from a copy I made earlier), and rebooted. At this point my GRUB broke, and I was able to restore it. At this point hibernation broke.
powercfg /h off and
powercfg /h on, rebooted, and nothing. Also tried increasing the hibernation file size as directed on this post, but it still doesn't work. Executing
shutdown /h yields
The system cannot find the file specified.(2). What file?
It seems that mounting the system partition sometimes works, but I don't want to keep it mounted in case it gets written to accidentally. How do I permanently fix this?
