I am already running Windows 7 Ultimate 64 bit OS in my HP 630 system (2 GB RAM, 320 GB Hard disk).
I want to do a full format of the entire disk & clean install a new copy of Windows 7 Ultimate 64 bit OS. When I restart the system with CD in the ROM already, it is not showing any option to start the system from CD (boot from CD). I changed the order of boot devices in BIOS & set CD as first option, still it is not showing me the option to boot from CD. Please suggest me how to go forth with full format of the disk.
Thanks in advance.
