Hey,
I made a switch to linux over 1 and a half years ago. It was a weird first step. However, you need to take the leap. Its more or less the leap of faith. There is a very low chance that anything will go wrong. There is always support if anything goes wrong.
To get you more or less started, try a LiveCD. This will allow you to explore linux without any change. It will load itself into the RAM at boot.
There is also an alternative called WUBI, it will install itself as a normal windows application. It should partition your hdd and load linux into it. It can be uninstalled like any Windows application too.
The WINE software is as easy as a command. The use of:
Code:
wine executable.exe
or editing wine.cfg.
