I tried all of them using boot repair none of them worked for me.
I was wondering, When I installed the system I created partition and mounted it as "/" and I installed the system on it. Do I need to create other partitions like boot, swapfile,,, ?
Honestly, you have nothing to lose by starting over from scratch. If it was me, that is exactly what I would do. Create a new bootable copy on USB or burn an installation disk. Format your thumb drive to FAT32, first. Redoing this ensures that there are no errors with the USB medium.
I am assuming that you are not trying to Dual Boot with Windows and assuming that there is not data on the disk that you fear losing.
If both of the above assumptions are correct, then create your bootable medium. If they are incorrect, please let us know.
In this link, you will find instructions step by step:

You would only need to set up your partitions if you have a different use in mind for your HDD. As above, please let us know if this is the case.
I would recommend that you do not create partitions at this time - UNLESS you are doing a Dual Installation alongside another O.S. If this is a straight installation of Zorin 15 to your HDD with no other O.S. on the computer, then a straight shot may help you get it up and running better.
You also do not need to create a Swap. Zorin 15 actually does that automatically for you during installation (Zorin 12 does not.)
It may seem like a lot of work to start over, but in actuality, you have already put in a lot of work. What your goal is is to get it installed and working.
As a mechanic, I can tell you... Sometimes you cannot just replace parts. Sometimes, you just gotta pull everything out and make sure each component is done right in one go, even if it seems like a lot of extra work. You just roll up your sleeves and get to getting dirty.
If you try to move a boot copy over to the existing installation, things will get messy. In my opinion, I think trying to patch it will yield less desirable results. I think there is no need to do so since this started as a fresh installation that was never completed.
