Hello, TanujMintLinux.
First of all: A swap device will not be mounted. It will only be activated. The swap mechanism uses the disk device, not a mounted filsystem.
In case you actually mean that swapping is disabled and that you have to re-enable it on every reboot, in this case I could imagine that the UUID of your swap partition has changed, but that the file /etc/fstab still holds the old UUID.
In short words verify and make sure that the details given for "swap" in the file /etc/fstab correspond to the facts.
Sample taken from my /etc/fstab:
Code: Select all
# swap was on /dev/sda5 during installation
UUID=d44a6758-8995-42ed-ac73-e39806848676 none swap sw 0 0
Note the word "none" following the UUID. It means "no mountpoint".
HTH,
Karl

and yes , something like-
" uuid #@%$^^^& no mount point"
comes written while booting
just clearly tell me what should i do so swap "ACTIVATES" on booting itself and i dont have to mount the swap partition i created after destorying the one at installation
and i just skip it

To do what karlchen suggested in his post:

Run the following command:
In the output of that command should be a line with a "TYPE = swap". The UUID of that swap file is probably different from the one you have in /etc/fstab.
If it is then edit fstab as root:
Change the UUID number of the swap line then save the file.
