The partition size was correct, but Windows 11 still was showing the old size for the drive in the Windows Explorer. But it was easy to fix with the Windows DISKPART tool.
I bought a new larger disk and wanted to clone all the data from the old disk to the new one. This can be done easily with many tools however I wanted also to increase the partition size, so it matches the size of the new disk and of course I wanted my Windows 11 still to be bootable and work as always. Why have I used Clonezilla?
