Looking at the specifications of you Lenovo have a 500 GB hard drive.
"there is no media hard disk"
I could be mistaken but it sounds like the CentOS installer doesn't see your hard drive.
Is Windows 8 taking up the whole 500 GB hard drive?
If so run this command as 'root' using the CentOS CD/DVD in the terminal and post the output.
fdisk -l (small letter L)
