i am browsing the iso with winiso and their is rvmintegrator.img can i delete this? Yes you can, you said about winiso, i recommand you opening it with ultraiso ...and from the menu Bootable use "save boot file" , so save it to any location you want on your hardisk with the .bif extension, then delete the file you want to delete, then entering the same menu of ultraiso , chose load bootfile this time..save the result, voila. But please might consider paying respect to the creator of this Integrator and his intentions ... "live or die, make your choice "
