parallels

okay, i have converted a uif.file to a iso.file. I have parallels and am trying to install it, i burned the iso.file to a disk and am having difficulty with parallels. It says that attempt had failed from harddrive and cd-rom..??? How can i install the windows iso.file into parallels..??? i converted the original uif.file to an iso.file using magic-iso program. any suggestions !!

thanks
