Computer booting problem

I have been facing this problem from last 2 days When i boot my computer,it stays on the motherboard logo for 25-35 seconds ,then says Boot from CD:Boot failed.I don't know what the problem is please help me.

Check these things in your setup menu

In the boot section,see that the boot sequence is set

1. CDRom
2. Floppy
3. Hard Drive

also make sure that your boot drive is listed first.

if you change anything make sure to save before you exit .

Hey Which type of Hard disc you have?
Please post your system specifications.
