The CD that comes with the retail box version of True Image 9.0 is labeled "Bootable CD" and hence is supposed to be bootable. I'd like to know how to boot the PC from this "Bootable CD". On the user's guide, I cannot find any instruction explaining how to boot the PC from the CD supplied with the retail box version. I put the CD into the built-in internal CD drive of the PC. Then, I turned on the PC. However, the PC persistently boots into the hard drive. According to the BIOS setting for the boot order, the CD drive has a higher priority over the hard drive. Do not ask me why I want to boot the PC from the CD though the PC can boot from the hard drive. I am not even sure whether this "Bootable CD" is really bootable. From the Windows Explorer, the only file I see on the CD is "trueimage 9.0_s_en.exe". Folder Options is configured to show hidden files and system files. I think this bootable CD is supposed to contain Linux system files and DOS system files to boot PC's. Did Acronis forget to include these system files when they burnt the CD? Or, are the Linux system files on this CD stored in a partition that the Windows Explorer cannot see? If this CD is really bootable, I would like to know how to boot the PC from this CD.
