    So here I am with being able to solve the problem.

    Following is the procedure:
    fdisk /dev/hda
    x - Enter to expert mode
    f - Fix the partition order.
    w - Commit changes.

    Modify the /etc/fstab and /boot/grub/menu.lst files accordingly.
    I'm done and everything is shown perfect.

    Now my questions,
    I did all this to solve the occasional hibernation problem that I faced
    which I suspected to be because of less swap space (My physical RAM is 768
    and my swap was 512).

    How many read/write heads does an IDE disk have (Eg a 30GB IDE Disk) ?
    Does having multiple swaps on one single disk enhance/degrade the
    performance ?
    Should I merge the two swaps to one single swap ?

    TIA,

    rrs
