I've done some searches here on the subject but haven't really found any answers that apply to what I want to do specifically. Currently running W7 ult x32 on partition 0 and booting with Daz loader 2.1 .. no problems whatsoever. I want to install Win7 ult x64 on a second partition (partition 1) but am unsure if the currently installed loader will "see" both installs at boot time. Would I need to reinstall the loader after the new install? And if so would I install it in both OS's or just one? Thanks.
