In my Ubuntu 12.04, the hibernation option was working well and fine. However, I installed Debian on another partition recently and when I again tried to boot to Ubuntu, I got a message on the boot splash screen saying :
The disk drive for / is not ready yet or not present. Continue to wait; or press s to skip mounting or M for manual recovery.
After logging into Ubuntu, I find that my hibernation option has gone missing.
Is there anyway to recover the hibernation option?
EDIT: I solved the disk drive problem and I got the hibernation option back. When I did "sudo pm-hibernate", my system went to hibernation. However, when powering on again, it booted up normally and thus there was no effect of hibernation.
How can this be rectified?
