edzha90 :
tried above functions but it won't boot actually it shows me I can press 'del' to enter SETUP and ALT-F2 to enter EZ Flash utility and nothing about F8 or any other booting information....
Are you pressing F8 right after the SETUP (BIOS) posts? you're supposed to press it every 1 to 1 and 1/2 second or hold the key till the Safe Mode boot options list appears on the screen. If the Safe Mode options list doesn't come up on the screen, the boot sector may be damaged, the partition could be damaged, or the hard drive may be dead.
As for setting the first boot order, do it according to the motherobard manual (BIOS section) and if still no success, the CD Drive may be damaged, may have lose connections, the master & slave jumper settings may be incorrecty configured, or the CD may not be bootable.
If nothing of this helps, you may have to give us some more detailed information to better understand the problem.
