I'm getting in problem when installing ubuntu 12.04 LTS with a CD-ROM.

After rebooting, There's a notice says, "DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER". Even though I input the cylinders, heads and sectors into the BIOS, it doesn't work.

Thanks for your help:) & Sorry for my bad English.
