I just got parallels and It tills me to stick my XP disc in the drive. I changed the CD/DVD Rom drive options so it can be read. I changed the boot order to CD hard drive floppy and everytime I hit the power button, The mac crashes and tells me you need to manually restart. I know this is a working xp disk. I use it all the time. but I do need help, I have also created the ISO of this disk and that don't work either. someone knows how to fix this. please help. thanks!
