Remove Windows on old :C, new :D drive?

April 1, 2018 at 13:14:24
Specs: Windows 10, 64 bit OS/4 GB
I have a new :C drive and my old :C is now my :D drive. It's getting full. Can I safely remove Windows on that drive to free up space or do I need it there? If yes, what's the best way to remove it?

Thanks in advance for your help.

Do you have a fully working installation on the new C: drive?

Shut down the computer, unplug the D drive and start it up again. If it starts normally then you can safely delete all Windows old files off of the system. If the two drives were plugged in while installing on the new drive, Windows installer MAY have overwritten the boot segment on the old drive and installed the rest on the new drive, this test will prove that the drive is completely self contained and does not require anything from the old one to operate.

I have done this many times over the years when building a new computer. Install a fresh copy of Windows on a new drive, then I plug in my old drive after the install was complete and transfer over all of my personal files. Then I would delete all partitions on the old drive, repartition and format it and copy back the personal files to the newly wiped drive. This way I am not bringing along a lot of junk that is not needed. By not having wiped the drive you may have many hidden files taking up space and never know for sure if you ever get most of them removed.

Thanks guys. Yes, there is a new fresh install on the :C drive.

Fingers I really appreciate your detailed reply. I'm a little reluctant to enter the computer and unplug the new :D drive; however, I had a compuer biz do this job for me. Am I correct assuming that I could call them and they likely be able to answer this question?

If the company who did the installation for you are half decent, then they should be able to answer your question over the phone; providing they can recall your computer and what they did to it?

Are all the applications you use also on the new C: drive?

I'm not at all current or familiar wth win-10 so what I'm suggesting will likely require a little more input from those here who are across win-10 in detail, in order to help you discover what's happening with regard to the second drive...

With NT/XP/Vista/Win-2K there was an option to view a list of all installed and bootable operating systems - via the boot-menu. Does that option exist in win-10? If so then with a little help form friends here you ought to be able to view that menu and report back what is shows. That will show (if I'm correct) whether or not the second drive is still bootable; as if it is then it will be in the list of bootable operating systems)? Likewise "some" of the apps/utilities there "may" still be usable via the OS on the C: drive, but no all of them; I know this from past experience.

If "all" the apps etc. you use are listed on the new C: drive then it's highly likely that the old (D:) drive is not really doing much in terms of allowing you to use the apps etc. installed there (on the D: drive)?

As Fingers suggests, one simple way is to simply disconnect the D: drive and then reboot and see if things are still pretty much as you have now - apart from the temporary absence of the D: drive.

If it is a small place or you can talk to the person who you worked with then you should be able to get an answer, they should know. You are especially good if they can tell you that the operating system was installed with only the one drive plugged in.

To use the method I suggested you need to be able to open the side of the computer (Unplugged!!!), ground out any static you have on you by touching the metal screw on any switch or outlet cover, then identify which is your SSD drive based on the brand/model number/size of the drive (smaller than a desktop drive) and remove the SATA signal plug (usually a flat wire going from the motherboard to the drive) from the larger older hard drive. There is no need to replace the case cover at this point, just make sure that the plug is not laying against a fan or where it might make contact with components. If it boots up and works normally then you just need to shut down, unplug fro the outlet, replug in the drive, close the case, plug in the system and boot it up again.
Note, I am assuming that this is a desktop computer, not a laptop or all-in-one computer. Compact cases may also be a little bit trickier due to the lack of space.
