Create swap partition

Question

I have an old pc (Dual core, 2gb ram (No graphic card because now is damaged) I used Windows 10 just for Work (My creative cloud subscription) and thanks to the subreddit [/r/unixporn][1 I've installed Freya (my first time in linux) and now I love linux and that OS. but when I installed Elementary OS Freya I did not create the swap partition (I did not know almost nothing about linux and so install it) but now my pc stays stuck in certain times and according to I have read on websites the swap memory help the computers with low ram memory (2gb or less) the question is:

How I can create the swap memory without installing elementary os again?

I have 4gb free space for the swap memory.

The swap memory it can cause problem with the windows 10 installation?

Hope that you help me, Im newbie in linux

This answer is after the discussion in chat

Here you have to do two things ,

1 . Deleting the /swapspace file created using AU question.
2 . Creating swap in unallocated space.

1 . Open terminal and run the commands:

sudo swapoff /swapspace
sudo rm /swapspace

2 . Install gparted,

sudo apt-get install gparted

Note Careful while selecting partition.

Open gparted and select unallocated space.

Right click on it , select new

Then select file system as linux-swap and logical partition(If not possible select primary partition)

Then , right click on partition and make swapon

Note Don't forget to apply changes

You can verify swap by the command

cat /proc/swaps

Next, add the following line to /etc/fstab to activate the new swap at boot:

/dev/sdb3 none swap defaults 0 0

(Replace /dev/sdb3 with your swap partition)
