The converse is also true: if you hibernate Linux, on boot you should boot Linux automatically, bypassing the boot menu. If you manage to boot something else, disaster can happen. BTDT. I hibernated Linux, then booted another Linux. This one opened some of the partitions that the 1st had mounted; saw them in use, did fsck. Next time, the 1st Linux booted, assumed (obviously) that the partitions were still opened and wrote to them assuming the previous state. Royal corruption issued. Fortunately, Windows can not open Linux mounts, normally. And Linux detects the hibernation state of Windows and refuses to touch it. The only problem is that Windows lies to the user, and instead of powering off it tries to be clever and hibernates instead. -- Cheers, Carlos.
