Help Please! Darwin/x86 Startup Problem

[slimvaio]

Hi I have burned the KALYWAY 10.5.1 DVD and when it goes to boot I get this message

 

-------------------Computer Screen #1-------------------------------------------

Use up and down keys to select the startup volume.

 

hd(31,0) Leopard_Inatall_Osx86

 

Press Enter to start up Darwin/x86 with no options, or you can:

Type -v and press ENter to start up with diagnostic messages

Type ? and press Enter to learn about advanced startup options

 

boot:

-----------------------------------------------------------------------------------

 

That is the first screen, when I push Enter it goes to

 

============Computer Screen #2===========================

Press any ket to start up form CD-ROM, or press f8 to enter startup options

====================================================

 

Then I push Enter to start up from CD-ROM and it just keeps repeating Computer Screen #2(above)

 

And when I push F8 it goes back to Computer Screen #1
