You could use a program like Ghost to make an image of the boot drive, then restore it to the other drive.



New drives often come with a CD that has a format/setup utility that will give you the option of copying your boot drive to the new drive. These utilities often work with drives you have lying around as well. You may be able to download such a program for free from the website of the company that made the drive you want to copy to.How to change my main hard drive,have two drives on a comp, the main one doesnt have enough space anymore?
This is not an easy thing to do, and you could lose data if you do it wrong.



Generally, you use a disk imaging program such as Symantec (Norton) Ghost or Partition Magic.



The safest thing to do is start with a brand new, large, blank drive, and image your C: to it.



The next choice is to make sure there's nothing you intend to keep on D:, then image C: to it. If there is data you must save, be sure to back it up somewhere else. And if there are programs on D:, make sure you have the means to reinstall them from scratch. The reason this method is risky is that if you forget to back up something, or improperly back it up, you will lose that data.
There isn't a straightforward way to do this, First question to you is do you actually have 2 physical hard disks in your computer? it may only be one and its got 2 partitions. If that is the case you could just extend the C partition and get rid of the D partition. If you have 2 physical disks then it starts getting more complicated, I would suggest the easiest thing is to uninstall all your progs and reinstall them onto D.
