My HD has 2 partitions, one for the OS (c: drive) and a second (unused D: drive) data partition. Just installed Windows 7 Professional on the OS partition - works great. My Questions - I had planned to put all my applications on the data partition but now I'm reconsidering and may want to put everything on c: partition, it just seems simpler. Another reason, I'm not quite sure how to make the installed programs always go to the D drive. Second question - Can I simply delete the d partition (Computer Management, Disk Management) and then make it part of the c drive? Suggestions greatly appreciated.
