Ok restart computer and when post screen apears you will prompted to press some thing like this F1/F2 or Del to enter BIOS/Setup.
Set first boot device in Bios/setup to CD/DVD put in operating reinstall disk press F10 to save and exit.
You will be prompted to press any key to boot from CD/DVD then do so.Do not press this again if you are prompted.Only boot from CD/DVD once.
Do not press R at first prompt just allow the disk to run then press F8 to agree to licence agreement you will be prompted to press R after this,this is called a repair install.
Or if that doesnt work then same as above first boot device set to CD/DVD rom put in disk etc.Then press any key to boot from CD/DVD then press R at first prompt this is called a recovery.
