Ok, let's say that i wanted to get a copt of suse 10...i make an ISO ..load it on my comp., then how do you get windows on there ? load windows onto the already loaded suse operating system ?
Nope, you have to install Windows first, because when windows is installed, the MBR is over written. Then, you Install your Linux distro. Usually, with a good distro/ installer it will automatically resize the Windows partition or place Linux on another hard drive. GRUB will be installed (GRand Unified Bootloader) and then, at boot time, you can select from it which OS you want to boot into, Linux or Windows.
If you are talking about WINE, you don't install Windows with WINE. WINE is used to run Windows executables on a Linux operating system. this can be done by running
$ wine name_of_program.exe
(at the command line).
