I've been using Linux for quite awhile, and the only reason I ever go into Windows is to delete stuff. I don't want to lose my current Linux setup, or any of my cargo.
I've heard of ways you can stop all Windows boot processes(Master Boot Record and others). The concept is to remove all interactions with Microsoft's OS from the very first stages of boot. Once this is safely accomplished, then you can simply erase the contents of that partition and use it as a FAT32 device, or you can use a partitioning tool to recombine partitions. I would rather recombine partitions because my single HD is only 40G.
My major concern about doing this, it may create conflicts that I don't know about, and I'll get stuck.
