Start up problem?

Hi,

I noticed a problem when my computer starts up,

It is telling me no hard disk detected then it tells me boot from cd/dvd then the computer starts up fine...

Is there any suggestions to solve this?

Regards

A little late to comment, but... Make sure the boot drive is first in the boot order in the bios.

Also make sure the HDD is connected properly and has power going into it. Does it show up in the BIOS as detected? Is the drive IDE or SATA?
