Question How can I merge partitions I cloned with Windows System Image Backup?

[Rodion15]

Hi,
I upgraded a 100GB flash storage card in a Toshiba laptop to a 500GB one. Then backed up the data to a hard drive and used Windows System Image Backup to transfer the data (which created the system + recovery + an EFI partition) to the new flash storage.
Now I find the partition has the same size and the rest is unallocated. I tried EaseUS partition master Free but it doesn't want to merge the unallocated space to the system partition (the unallocated partition appears rightmost). I wonder if EaseUS or any other free partition manager can do this.

Any way to do this with Windows default Disk Management?, I like using default Windows software without resorting to third-party tools.

Any help much welcome.
Antonio

Windows and some partitioning SW will not let you do anything with a partition it's booted from. You could make a bootable live USB with https://www.majorgeeks.com/files/details/gparted_live.html and do it from there.

Thank you, I'll have a shot at that.
