I know there has been similar posts here, but it did not make me feel that it is answering my question.
I have done dual-boot installation previously with Debian. What I did was used an Ubuntu CD to install it as an application on Windows Vista. Therefore, when I start the PC the dual boot menu appeared normally. However, I did not have to go through all the usual hoops of partitioning etc. And the really "Good" bit of all is the facility to uninstall Ubuntu from Add/Remove program option from WIndows Control Panel. I really liked this.
SO WHAT IS THE PROBLEM?
Ubuntu is very poor when supporting third party drivers, especially for wireless. I could not connect to the internet as my wireless driver was not working. At that moment, I had a Dell Studio 1535 laptop with a Broadcom bc4312 wireless LAN card. Later on, I realised that my Broadcom bc4312 was in fact, a phenomenal nightmare in Linux community as nobody could actually fix the driver problem. Nevertheless, I changed my laptop last year to Lenovo Ideapad V470 and should have a better wireless card to be supported by bespoke Linux distrib. And the word is that Debian is the most robust distribution when comes to supporting third party hardware drivers.
WHAT I WANT TO KNOW
If I download ISO from Debian site and then create a CD, can I still do the similar installation as I did with the Ubuntu? If not, then its fine I won't bother anymore. Essentially, I don't want to do anything with partitioning. I just want to install it, try a few UNIX-y things myself and when I am satisfied, I will use Debian for my home server OS. In short, I want to try debian without having to jump through hoops.
UPDATE I forgot to mention that I would consider virtualisation e.g. using virtual box to run an image on Windows desktop. Nevertheless, it would be good for my purpose to do it in the way I installed Ubuntu.
