Although we are happy to help those in need, what you are asking for is a tutorial on basic UNIX/Linux system administration.

In order to become more proficient, and have ready references at hand, may I suggest that you begin to acquire a library to assist you.

There are many excellent texts in the USD20-30 range as well as probably some material at your local liibrary.

Your system itself should be your first source. Learn to use the manual pages installed at your system. The command: man , followed by almost any command or configuration_file_name will give you basic information concerning such and often references to further information. The command: apropos followed by a search string will give you a list of the manual pages that include same.

In your case: man fstab , man reiserfs, man mount, man partimage, man cp, etc

If you really get stuck, please post with the exact command that is giving you trouble.

The comment, " I am now trying to mount that partition but it say's I need an entry in the etc/fstabs file", does not give us much information and simply makes a reply more difficult as we have to guess what your likely actions were.
