Best Practices

If you are installing Windows on a bare metal machine (new hard disk with no Operating System installed on it) you should create only one partition of the size of your choice and leave rest of the hard disk space unallocated. After Windows is installed you can change the default CD/DVD drive letter from D: to something else. After this you should start creating other partitions on your hard disk drive. If you have executed this in a planned way you will notice that after you have created all the partitions your drive letter assigned to CD/DVD drive comes in the last. ((For example C: D: and E: for primary partition and logical drives and F: for CD/DVD drive.)
