4.When you want to use the recovery center, put the CD in your drive and boot from it. This is usually done by pressing F8 Or F12 at startup, or changing the boot drive order in the BIOS.
5. It may search for the OS then a repair popup will be there then just click ok and restart after that let the recovery disc pop up again then restart without disc.
This may or may not start it up, if it does not you will need to reboot the Repair CD to run Startup Repair up to 3 separate times with reboots to repair or rewrite the MBR.
