Hello, i need to install two or more windows XP, completely independent and i want to boot each one, depending the user that want to work and modify the files corresponding to these installation only. So, i need to hide the non booted partitions in which the others instalations are placed I've defined 3 primaries NTFS partitions and drop images of one installed partition image (using True Image 9.0), but the most close to my goal, that i find myself is to share the same installation. ( ex: i created a txt file, and put it in the destop , when i boot another user, the file is in the same place !!!) How can i make the installation, to work the way i need? Thank you for your time, Regards P.D. I tried to do the same but instead WinXP, using Win98 and it works really fine..
