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
