is to partition the hard drive and load windows.
You haven't mentioned which version of windows you are going to use but if it's XP or Vista you partition the drive as you configure the windows installation.
You must set the computer to boot from the cdrom drive and start the installation.
When it gives you the option to load windows onto the drive, you must delete that partition. The option is to delete with a D.
You must then rebuild the drive on the next page, this just means pick the size ( in Mb's ) of what size you want your C drive.
It will then finish the installation of windows. load on your drivers and software.
Then right click my computer and pick manage. then go to disk management and open it. You C drive will show with a lot of unallocated disk space to the right. Right click on this space and create the new partition and format the drive.
Put a tick in the quick format section to format the drive in seconds.
When done, post back.
