-HELP- What the FUCK is "Non System Disk"????????

[CutMeMick]

Need technical support.

I want to install a program on my PC.
As a side note it reads:

*Note: For Vista users, it is recomended to install this program to Non System Disk.


Can anyone explain to me what this means in "dumb ass terms"?
I know a system has several disks but what does it mean by non systen disk?

weird.. is it an older program? Something on it is probably not compatible with Vista..

I have Vista and i have issues here and there.. like i wanted to put in my old hard drive to get stuff off of it, and because it was IDE it wouldn't detect it as a hard drive, just as a dvd-rom.. stupid..

No it the latest version.
I think more then anything it just want's to keep my PC safe.
