While UbuntuForums is a great means to get solutions for your problems, UbuntuGuide is the place to go to find new tricks and apply them in your system.

The Hardware Support page shows a hardware compatibility list that you can refer to before you make any hardware purchase. This hardware support page is maintained by the community and anyone can add/modify the entry.
Ubuntu Documentation
It is no doubt that Ubuntu is an easy to use and user-friendly distro. However, if you are still having difficulties navigating around and get it to perform simple daily tasks, you can head on to Ubuntu Documentation and read about everything you need to know about Ubuntu. It won’t make you an expert, but at least it can help you to get started (and perhaps show your friends how geeky you are).

Differences between Ubuntu (Public software) v/s Proprietary software (Microsoft Windows):

Is Ubuntu compatible with Windows?

Yes. Installing Ubuntu does not stop you from working with your Microsoft Windows files and applications. Ubuntu can be installed along-side (side-by-side) Windows and also it can be installed within Windows as a program. However if you use Ubuntu you may not need to use Windows since most of the applications on Windows are also available bundled with Ubuntu, like Office, Web browser etc

Why is Linux/Ubuntu less prone to Malware/Viruses?

Linux is based on UNIX architecture. UNIX is designed as a multi-user operating system and has in-built safeguards to protect user from malware. This includes user permissions definitions, user space distinct from system space etc
Programs are run as normal user, not Root User.
Vast diversity makes it difficult to reproduce flaws in a system.
All software and drivers are frequently updated by Package Managers.
Software is generally installed from vast Repositories not from unfamiliar websites.
No-one profits from supplying anti-virus or security products.

Here it shows that /dev/sda1 is your Windoze partition. /dev/sda2 is your new root partition. And /dev/sda3 is your SWAP space.
