    Hibernate between 2 OSes, without reboot possible?

    Is it possible to hibernate both windows and ubuntu, and switch from one to the other without doing a full reboot ?
    It would be nice to have a quick way to dual boot a machine, and that's the closest thing I can think of that's kinda doable.
    Perhaps there's some way to return to GRUB without rebooting the pc, that would basically do the trick.
    I want to live in this alternate universe T___T

    Interesting, but probably not possible (yet?).

    My laptop does this. When I hibernate Ubuntu is basically shuts down with the session saved. When I turn it back on I get grub and can select Windows if I want. And when I reboot into Ubuntu it just comes back from hibernate.

    It's possible, because Windows (at least XP, the one I tried with) and Linux store the information in two different places: Windows in some file in its partition, and Linux in the swap partition. You should need no extra configuration, just hibernation working on both OS's.

    If I got it, the OP does not want to reboot the pc. As far as I know, there's no solution for this case (up to now). There is no way to switch the operating systems without rebooting.

    The closest thing you can get to 'switching' OSes without a reboot is virtualization, but you won't get the full capabilities of Windows if you run it under Linux.

    This is how it works on my laptop by default. If I Hibernate in Windows and bootup the GRUB menu loads. Then I can go into Ubuntu. After I am finished with Ubuntu, I can unhibernate Windows.

    You could of course use sometinh like VMWare, so running it virtually.

    You're right, this can be done, not only in laptops, but in desktops and servers and whatever else that supports dual booting . But it seems that the OP does not want to reboot the computer, and that's the problem. I don't think you can switch operating systems without rebooting.
