Disk size shows the same after cloning a small disk to a larger disk

cloneclonezillahard drivepartitioningssd

I am running Windows 10 Pro and I cloned (disk-to-disk) my 120GB SSD drive to a larger 2TB SATA drive because I was running out of disk space on the 120GB. I used Clonezilla and everything finished successfully.

After cloning, I removed the 120GB SSD drive and booted from the 2TB SATA drive Windows loaded successfully, but in File Explorer, it show that the C: drive is still 120GB and the new 2TB is not shown.

In Disk Management however, the new drive is shown with 4 partitions: 100MB System Reserved, 120GB (C:), 450MB Recovery Partition and 1751GB Unallocated.

How can I increase the size of Drive C:?

Best Answer

The remaining GB (difference between 120gb and 2TB) of your hard drive are free and must be manually assigned to a new partition or assigned to drive C (Resize the partition)

You can do it manually. In Windows, go to Computer Management and Extend disk space. If you do not want to do it manually you can use applications like AOMEI Partition Assistant Standard, GParted, etc.

No need for external tools. You can fix this issue by using the diskpart tool from command line. First open up the command prompt window. Then type diskpart to start the tool.

Within the tool use the following commands to extend the file system of the disk in question.

list volume
select volume #
extend filesystem

Replace the # with the volume number that you see after entering the list volume command.

Windows – OS does not boot after cloning from HDD to SSD

Most probably there are couple of problems. One is the fact that you're copying only one of the OS partitions while the dualboot is usually handled by the Unix loader.

The other issue could be the software itself, since it does not copy the windows boot partition (the *:) correctly.

My suggestion is that if you want to copy only the windows OS, just go ahead and clone the unnamed partition and the one containing windows. Then disconnect the HDD, run windows installation disk or USB and select the repair option. This will almost certainly fix the boot process.

If you want to keep the existing state, do a whole disk clone, and you could use software later to move and resize the partitions as you wish. Hiren bootcd contains what you need for this. And you can use Rufus to make bootable USB
