To all of you who are uncertain of this, I can verify that you do not need any kind of Trick & Cheats to do this.
This i not a guess or just me blabbing empty words, I have done this several times already.
When I set up a PC I always delete all partitions including the recovery partition, I will never ever need this. Of course I always ask people and explain what this means before doing so on others machines.
But by deleting all that crap the manufacturer installs gives you an entire better feel and overview of your setup.
