The changes to files, registry and more run so deep and there is no tool to automate this that when you see the wrong drive letter you STOP immediately and start over before you invest too many hours on an install that some will not be happy with.
Windows xp was installed on a 2nd hard drive in a 1.6 gig computer and files transferred to new drive- this wad done before old drive had a chance to crash-then the original drive was removed . the new drive came up drive F, due to other cd drives and card readers. I need to change the new drive to drive C,many downloads from the internet won't load because they are looking for drive C. Can drive letters be changed without wiping out F and starting all over again ???
