First Thing First


You need to learn new Terminology

You do not go to a site for downloading the software but you go to a 'repository  '

1. Repository  It is storage location where one or number of  package's ( software) are stored

2. Package   well for window user it is software only.

3. Source.list : it is the file where all your repository's address is stored

So You need a Package now. Go to an application Called Ubuntu Software Center and search for the package.


if package is there and install is written in front on it just press install and job is done.

if not then see my next post

Tryst with Ubuntu (Linux) -a long time Window user

Linux keeps attracting me because of its free nature , free from viruses and fast speed .
The idea of  sharing your knowledge is very attractive.
So many versions of linux are in market .
Ubuntu is one, which i installed on my laptop along with windows Vista.
As I was beginner for Ubuntu so I let the Ubuntu install  on its own without any manual partioning.
So romance with Ubuntu continued for some days.  After some days i deleted one windows partition for some space and  next i realized that my computer did not boot saying grub failure .

Word Grub was new to me
GRand Unified Bootloader (http://www.gnu.org/software/grub/)

Searching on the net i came to know that Grub is a boot loader for multiple boot systems and i must have accidently deleted Ubuntu partition containing Grub loader. My First Heart Break

So next thing was how to correct this problem.

So after lot of searching i corrected this problem by correcting MBR ( Master boot Record) by a free utility ( link i will post soon) and Windows came alive

I thought i will never use Ubuntu again as it put it wasted lot of my time . ( I was wrong i am again using Ubuntu now i will tell you why in my next post). But i learnt a lot of new things which is helping me in my second affair with Ubuntu. I hope this will be a long association.
