Windows 10: how to move C drive from SSD to HDD?

I have a Windows 10 desktop. My problem is that the C drive is a small SSD, 120G. I have tried to install programs to D drive whenever possible, but C is still full. I want to move my C drive SSD and merge with the existing D drive HDD. What is a good way to do this, without re-installing Windows 10? If it is hard to do that, I have a larger SSD 240G. How can I move my C drive to the larger SSD? Thanks!

Windows 10 on HDD to a new SSD

I have recently replaced the 500 GB HDD in my laptop running Windows 10 with a 480 GB SSD. The laptop was fully configured with my applications and other settings. The steps I took were as follows:

1) Shrink the C: drive so it was significantly smaller than the SSD (by at least 100 GB) using the Disk Management tools in W10.

2) Copy all the files from D: onto an external HDD.

3) Download Ubuntu Linux and burn on to a DVD.

4) Download Windows 10 from https://www.microsoft.com/en-us/software-download/windows10 and burn this on to a DVD.

5) Close down and boot the laptop from the Ubuntu DVD from step 3 (I used a USB DVD rewriter).

6) Plug in the external HDD.

7) Open a Linux terminal and cd to the external HDD.

8) Copy the C: partition to the external HDD using a command such as:

dd bs=1024k if=/dev/sda1 of=C-drive

where sda1 is adjusted to point to the correct partition.

9) Close down and remove the external HDD.

10) Remove the HDD and replace with the SSD.

11) Perform a clean install Windows 10 from the DVD from step 4. Deleting all partitions from the SSD if it has had any created on it. When it asked for the product key, there was an option to enter it later. Make sure that the C: drive that is created is
the same size or bigger than the C: drive was on the HDD.

12) Repeat steps 5, 6 and 7 then run the command

dd bs=1024k if=C-drive of=/dev/sda4

With the clean install of W10 64bit, sda4 was the C: drive on the SSD after the installation.

13) Reboot from the SSD. The first couple of times my laptop reported errors and went into repair and diagnostic cycles. The last one said something like Reboot or Go to further tools. I cannot remember the exact messages but the meaning was as I have described.
I rebooted and Windows 10 came up and ran perfectly.

14) With the SSD working I shrank the C: drive a few GB to make sure the physical space was the same size as the actual filesystem.

15) Create a D: format it and copy all the saved files on to the new D: from the external HDD.

Job done. All my applications worked perfectly and the laptop connected to my wireless network without needing the pass phrase re-entering. I had tried several other ways of cloning the HDD to the SSD, but as the SSD was 20 GB smaller this was the only way
I managed to get it to work.

I hope this helps others to make the HDD to SSD transition.

 

OS on new SSD, keep existing data on HDD and use as external drive

Hi,

use steps you suggested, there should be no problem.

Just replace HDD with SSD first then run installation. Do not forget to remove Windows files from HDD after the end of a process.

 

Confused about hard drives: HDD and SSD

Browsing through the Microsoft Store for a new pc, I see various hard drives listed, such as:

16GB eMMC

32GB eMMC

500GB 5400 RPM HDD

2GB DDR3L 1600 MHz

32GB SSD [?]

64GB SSD

I understand that solid state drives are good, though expensive. What I don't understand is what size of an SSD would be the equivalent of, say, a terabyte HD? It seems that 64GB is the largest SSD offered here. What size HDD would equal that capacity?

And, BTW, what is an eMMC?
