One HDD showing as two Disks in Disc Manager

[kalle.wester]

Heya!

I've just cloned my old 500 gb HDD onto a new 2tb HDD using sudo dd on a usb linux install and all the data is intact, but when I went to extend the partition in Windows 10 it shows the HDD as two separate disks, the actual HDD and the partition of the HDD that's my old data.
When I try and use Extend Volume on the disk shown as D: then it throws a warning about turning the basic disks into dynamic disks.

How should I go about extending the partition to be the whole of the 2 tb disk without messing anything up and/or losing data?

I'm sorry if the answer is painfully obvious, I'm famous for overlooking stuff right under my nose.

Edit: The command I used to clone the drive was "dd if=/dev/sdc of=/dev/sdd bs=100M"

I'm guessing that "Disk 1" with the storage pool and unallocated space is the disk you are referring too, correct?

Yes, Disk 1 is the new HDD, the "Storage pool" on it is what's identified as Disk 3, my old data, which I want to take up the entire space of Disk 1. I could just go through with turning the disks into a dynamic disk but I don't want to do that right now as I don't know what that means.

What did you use to clone the data?

Does it give you the option to merge partitions?

I used https://gparted.org/liveusb.php on a usb to see if I could clone it with that, but it failed to identify the original drives data structure, so I used "dd if=/dev/sdc of=/dev/sdd bs=100M" in a terminal and that cloned it all fine, everything is intact, but now this happened.

Maybe I should tag this topic with linux too since I used that to clone?

The standard Disk Management in Windows 10 doesn't seem to give me that option. Of the options that appear, only "extend" would come close to what I want, but that would also make it recognize the disk as two dynamic disks.

Do you think I'd be able to clone this onto the unallocated space on my HDD and then delete the original, after which I'd be able to extend it as a single Disk? That seems like a really roundabout way to just make my computer realize that it's actually one disk.

I gave up and reset the new HDD
