I just received a new laptop, and for some reason, the manufacturer decided that one great C: drive and no other (user available) partitions were the way to go. I would like to have two partitions - one for OS/Program files and one for my personal data (documents, photos etc.).”

Have you ever confronted the same situation that this user had in Windows 7? Maybe you got more than one partition on the hard drive yet in a big C: drive with redundant space, and you want to split partition C to get some space for other purposes. Maybe you have to shrink C drive for other reasons. Anyway, how to create partition in Windows 7 from C drive is what you need to consider next. 

Tips: whenever you try to do something on your hard drive, please back up disk first in case something bad happens. You cannot be more careful with your data even though this operation has no harm to it.
