Formatting option while selecting custom option...
In my laptop existing OS is Win7 Home Premium x64.
Hardware config is
HP i7 Quad processor 1.7 GHz.
4 GB DDR3 Ram,
500 GB HDD.
My system perf is slow. I installed few softwares. I have deselected most of the startup services and programs from msconfig. Eventhough my system bootup time is slow, and whenever i open mycomputer it taking time to load.
I have decided to install Win7 Enterprise Edition x64 by formatting my C drive. But there is no option while i do clean install. Please help.
