almost all installers for software actually call the PROGRAMFILES environment variable, which directs the installer to the proper directory regardless of whether it’s on C, D, J, or Z.
there might still be a few poorly-written programs out there that hard code “C:\Program Files” into their installers, but they were developed incorrectly and probably suck anyway.
with modern Windows versions there’s really no cause to worry about the system drive being something other than C:.
of course, it would be even better if Windows would use more generic mount points, but 30 years of history is hard to undo.
When your drives show up, take a look and the partition.
Right Click -> Advanced -> Change Drive Letter -> Choose none (for the boot partition)
Then find the partition you want to be the “C” drive, right click -> Advanced -> Change drive -> Name it “C”
Then follow the same steps and name your boot partition “D” drive.
It may not work but it’s worth a try.
I recall a while back the Google Browser could only be installed on the “C” drive, it wouldn’t let you choose. I don’t know if that is true or not still.
I just thought this could be a bit tricky as you’re going to have to install EASEUS on a drive and when you change the letter it will cease to work.
You’re going to have to have at least three partitions for this
Current
C drive -> Boot Partition
X Drive -> Unknown
You might have to make a third partition to install EASEUS then change the drives leaving the drive letter you installed EASEUS on alone.
Then if it works you can uninstall EASEUS from this temp partition and reinstall EASEUS on the now correctly named C drive and use EASEUS to reclaim what’s left
Maybe I’m overthinking this
Sounds like it’d be easier to start over
Now that I think this over, I don’t think it would work to rename it. All your registry values are going to be in “D” drive and changing the drive of the O/S isn’t going to change that.
I’ve done something like this and made it work. It did take a long time, though. I had to search through the registry for D: references and change them to C:. I also had to do things with the boot ARC paths. It was slow, hard work on Windows 20000, but I was being paid to do it. I don’t recommend it on Windows 7.
Your fastest solution is to back up, delete all the partitions on the disk, and reinstall.
And in the year 1984, after numerous failures in the mobile and tablet arenas, Microsoft leapfrogs the competition by moving directly into spacetime manipulation. From its humble beginnings on Planet C:, the Windows family of physical laws now power more than 98% of life-supporting universes…
The most surefire way would be to reformat and reinstall windows with the drive partitioned the way you want. Since you’ve just done it recently anyhow it should be less painful than if you were concerned with backing up all your files on a system that had been up and running for years.
