First of all I am a novice when it comes to OS and system installations, etc. So, excuse me if I'm asking stupid questions. At what point during instalation I have to watch out for "chose repair installation"? I mean, will there be any window asking to pick the repair option?

My situation is: my office computer came with professional (with softwares like AutoCAD, ArcGIS, etc...) and many times I felt the need to use my laptop for my office work. So, just thought that using the "frequently-used-work-related-softwares" installed on similar OS (professional) might be a good idea. I may be wrong here, but please suggest on this and if possible a step-by-step process of installation.

Thank you once again.
