My hard drive has had 2 partitions since installation, the normal C drive and a D drive, both were loaded with MS Windows 2000. I had a problem so now have Windows XP in the D drive and a faulty operating system in the C drive (it will not run and asks me to install the original set up disk). I have manipulated the partitions using Paragaon Partition manager to enlarge the D drive and reduce the C drive to practically nothing. I would like to merge the drives but wonder if this is possible without first installing Windows XP in the C drive and if it is then would the C drive take over; I want to keep all the programs etc that I have in the D drive. Has anyone done this and if so cqan they give me advice.? Thank you.
