I had to reformat my Mac because of some problems. Now, I am trying to reinstall windows on my Mac, so I upgraded the program from what version I had on disc to RC2 candidate. Installation of XP works fine for some time, but then it starts saying that one more more files could not be copied and to press enter to retry. If I decided to skip it, then it says windows may not work properly, and brings up that same message later. I also tried uninstalling parallels, but I cannot downgrade to the version that is on my disc. How can I get windows to install properly?
