hi, i have rebuild the CentOS and make a bootable cd. also i have change the productpath from CentOS to Sal. durning the install process. after set the root password. an error occurred once i click the next button. the error is "An error occurred umounting the CD,Please make sure you're not accessing /mnt/source from the shell on tty2 and then click OK to retry" but actually i install the cd with vmware so i can't use tty2. so besides change the anaconda source . which files alse i should edit?
