I have my own linux comatible lab. Vista and other windows system not frendly to linux from install. If you try to install windows after installing linux it's completle erace linux bootloader. When you install linux after windows then in linux bootloader you can choose to boot linux or windows. And there more issues in compatible windows with linux. How about detecting partitition type in windows installer an d disk manager and maybe read linux files (you can access windows file from linux)
