Install From an ISO File

In Ubuntu, determining the mount point of an ISO file is very difficult. Unlike windows, we cannot use the setup option for most cases in Ubuntu. Here's a simple way to install from an ISO Image:

1. Create a folder in a suitable location.
2. Right click the ISO Image and click "Open with Archive Manager".
3. Extract it to the folder which you have created.

This solves the initial phase of the problem. Now, we need to install it. If you look at the contents of the extracted ISO in the folder, you will find a binary with a name install.bin or setup.bin or something of this kind. Now do the following

1. Open the terminal.
2. Login as root(su -).
3. Change your path to the folder path(Suppose the path is /home/user/extract then type " cd /home/user/extract " without the quotes).
4. Then type ./filename.bin.

There you go!!! Installing from an ISO made simpler!!!
