i had similar problems with xp and grub also new to ubuntu so i resolvse it by using removeable trays with seperate hard drives for each operating system set them up on primary controller i shut down exchange system h/d and reboot just a method that i chose to use because i feared losing all my previous work which is like 20 years of windows files and routines this way one operating system cant effect the other similar to having two computers
