I am tying to mount a second hard drive to my server with CentOS installed on the primary hard drive. I need to get some data off of the drive. It also has Linux installed on it. It was the primary hard drive on the system it was installed on. When I set it up as the second disk it will not boot the drive because it has /boot partition on it. So it conflicts with the /boot partition on the primary drive. How can I boot up the computer so it sees this drive so I can move the data across to the primary drive.
