Well, some educated guesses maybe..I don't think you have to worry about file and data corruption because of the difference between ntfs and fat32..winxp is more than capable of running on either file allocation table type. Windows xp by default looks for other installed operating systems and sets up that dual boot configuration by making drive c the system boot drive..if you look in drive c directory, you will probably find a boot.ini file installed by xp. In order to get your boot magic to work again, and possibly get your winME folder hidden again, I would uninstall and then reinstall boot magic on the root directory of the C drive. This should give you the option to hide the xp partition and get boot magic to be the default boot manager. If you have problems after this, you may need to edit the boot ini file..let me know
