Hi,

I just cloned my Windows 10 boot disk from a 120GB SDD to a 1TB SSD. I wish to extend my boot partition to use the entire space. This is what I see in disk management:

The unallocated space is disjointed from my C:. How can I join them?

Is it safe to remove the 450MB recovery partition? This is a Windows 10 installation that was upgraded from Windows 7. I don't need to recover the Windows 7 anymore.

The easiest way to expand your C drive is to clone again and use PROPORTIONAL mode. That will expand all of the existing partitions so as to fill the larger drive.

Without re-cloning, is there anything I can do to extend my C:?

All of the advice was good, but nobody answered this question. It is not even clear to me that the 450GB stub is the EFI partition for Win 10, but it's no more clear to me that the OP is using MBR or GPT.

In a dual-boot with different volumes or boot partitions for W7 and W10, the removal of the W7 is fairly straightforward, with the first step at removal of W7 from the boot menu using msconfig. It was never entirely clear to me that you could delete the 100MB system-reserved in addition to the W7 system-boot partition. If you don't, you could be wasting only 100MB on the storage device and nothing to fret about.

On a GPT dual-boot, the EFI stub is more likely following immediately after the 100MB sys-reserved, but my recollection of the same OSes in MBR is identical to what is shown by the OP.

The licensed version of Easus PM will convert a dual-boot MBR configuration to GPT. You can only ask the question as to whether it's worth paying for.

UPDATE: NOw that I think about it, the only reason my 100MB s_r_ and 300MB EFI were only made contiguous by EaseUS [licensed] PM during the MBR->GPT conversion, and there was a choice-dialog that pops up asking if you want to do it.
