Use fedora10livecd to start up!

Use fedora10livecd to start up! -- Linux general technology-Linux technology and application information. For details, refer to the following section. Yesterday I carved a live cd of fedora 10 to try fedora 10.
However, an error occurs at startup:
Instead of accessing the desktop, you can access the command line. The following message is displayed:
WARNING: CANNOT FIND ROOT FILE SYSTEM
Creat symlink/dev/root and the exit this to continue the boot sequece
No job control in this shell
Keywords: "WARNING: cannot find root file system"
All are English posts. You can see it clearly. Some say they need to be burned again, some say they do not support hardware.
Have you ever encountered prawns with the same problem? Give me some advice !!
In command line mode, the dev folder is used to run the ls command. But there is no root folder (Note: I did not find it. The directory cannot be directly accessed by cd/dev/root .)
Thank you !!
