Basic wine questions and dual-booting
I just installed Wine, but I am not sure how to use it. Since I dual-boot(windows vista, ubuntu), should I try to use wine to access the programs from my windows partition, or just install them on the linux partition and then use wine?
I am worried that I may mess up windows by doing something on linux and vice versa. Is that possible? How about if I am using Wine and I attempt to access windows files from Linux(I did try this, but I don't know if it actually accessed anything)? Is it possible to modify files on my windows partition from my linux partition(with or without wine)? If I have a virus on my windows partition, could it spread to my linux partition?
Running programs when installed in windows already
Back to your original question. You will have to install the apps you want to run under wine again. I am no expert at Wine but even if you installed Windows on a second partition and booted from it you would still need to re-install, you couldn't simply click on the .exe file and run it.
The reason for this is window program installations usually scatter crap everywhere. Some programs copy .dll's to the system32 directory, they write to the registry during installation and may also have .ini files that are created as part of the install process. It is durn near impossible to copy a Windows program directly from one system to another for this reason. Unless wine is using some serious voodoo you are going to have the same issue there. On that note you could probably mount the windows volume and use the same data files once you have your programs running in wine..
