First things first. What does hibernate option in Start menu mean ? In simple sense, hibernation means a power saving state. If you are going somewhere and won’t be using Computer for an extended period, then you can hibernate the Computer for sometime, and thereby saving power. This is useful especially for laptops, because their battery may drain out soon and there may not be a source to charge the battery. This hibernation will put the programs on hard disk, and then it will turn off the Computer. Hibernation uses the least amount of power, compared to other power saving states of Windows.
What does sleep option in start menu mean ? Like hibernation, sleep is also a power saving mode. Sleep allows you to quickly resume the work, within a few seconds. But one important point to be noted here is that sleep puts all the programs and settings in memory (RAM), and keeps drawing small amount of power, unlike hibernation, which puts settings and programs in hard disk.
Hope this will clear the confusion and it explains you the difference between Hibernation and Sleep in Windows.
But sometimes it may be possible that hibernate option is not displayed on start menu, or you may also want to disable hibernate to save some disk space.

How to disable Hibernate using Command Prompt:

Now this is done. When you open start menu, and click on that side arrow, there would be option for Hibernate and Sleep.
In case, there is still not option for hibernate, then click on Start and type Power Options and press Enter.
In the left hand side, click on Change when the computer sleeps. Now click on Change advanced power settings.
Expand Sleep and there should be an option for Allow hybrid sleep, just turn OFF this setting and click on OK. That should solve the issue.
