I recently installed Ubuntu 13.04 alongside Windows 8. Ever since then, I'm not able to put my computer to sleep in Windows 8. I click sleep, and it goes black, then just turns back on. After some digging, I found this thread (http://ubuntuforums.org/showthread.php?t=1341694) from a few years ago. I followed the instructions the guy suggested, but it didn't work. Was I supposed to remove the boot flag from the Ubuntu partition as well? Any ideas?
I've tried using EasyBCD to make Windows 8 my default, but it didn't work. As far as I understand, the reason Windows refuses to sleep is that it's not the primary boot drive or something.
