Windows doesn't hibernate

Hello. First of all thank you for making this tutorial.

I followed it thoroughly and unfortunately I still have no hiberfil.sys file. The system locks, the screen goes into energy saving mode, but Windows doesn't hibernate.
It all began when I upgraded Ubuntu (have a dual-boot), made a clean install of the 12.04 version, seemed to get all partitions encrypted, then messed up the grub, and finally I had a hard time assigning auto-mount and read-write privileges to all of them.
Ubuntu seems fine now, and Windows sleeps but can’t hibernate (or allow the hybrid sleep). Windows’ partition is listed as “boot”, I disabled the option of auto-mount for Ubuntu, but it still doesn't work.

Any ideas of what could be wrong?

If you installed grub in the MBR, Windows won't hibernate (or hybrid sleep) - it requires the Windows bootloader. You can install grub on the root partition of your Ubuntu install, then re-install the Windows bootloader to the MBR and add a menu item for Ubuntu - I've been dual booting this way for years.

I use EasyBCD for both tasks - reinstalling the bootloader and creating the menu item for Linux. It's free, and is very useful.

sgage, thank you very much for the reply.

I'm researching what I have to do to follow those steps you mentioned. As soon as I put it into practice I'll post the results.

run cmd as administrator and execute : powercfg -h on

Hello, thanks for the reply. I'm afraid I had tried that several times, and it didn't work.

In Ubuntu, run the following commands:

sudo grub-install -f /dev/sdax (where "x" is the number of your Ubuntu partition)
sudo update-grub

Then, boot to Windows. Download EasyBCD from

EasyBCD - Take control of your boot loader | NeoSmart Technologies

The link for the free download is towards the bottom of that page.

Run EasyBCD. I'm in Ubuntu right now, so I can't remember exactly how it looks, but there's a selection for "Add Menu Item" or something like that. Simply go in there, click the tab for Linux, tell it grub2 (vs. legacy), and save. Then look for a selection which I believe is called "deployment" or something like that. In there you can very easily install the Windows 7 bootloader to MBR.

Next time you boot, you'll get a menu with Windows and Linux, and you're all set...

sgage, thanks for the very detailed instructions, unfortunately it still doesn't hibernate.
I also ran a chkdsk -r, and I made all partitions available for read-write.
The only thing left to try (that somebody else suggested) is updating the BIOS, if that works I'll update the thread.

No what's left is to wipe the HD to Clean Reinstall Windows 7.

GRUB can also corrupt Win7 beyond repair when on the same HD.

Even if you move GRUB to Linux partition and rebuild the MBR using EasyBCD or Partition Wizard, you will not have the Repair console on the F8 tools which requires running Startup Repair - Run 3 Separate Times after Marking Win7 Partition Active. You can try that now to see if it resolves your problems, but cannot count on it.

Finally!!! It works now, I followed the advice given here:

Thanks all for your time and advice.
