OK, thanks. This is encouraging. But there´s more to it. As they say, the devil is in the details...:
I have my LM13KDE on a USD disk and when I was installing it, the installer offered setting aside:
1) the first partition (with FAT32 filesystem which is freely accessible as a data storage - by both Linux as well as Windows)
2) next as the second partion Linus OS has been installed and then also
3) the third partion was created for the swap file.
If I get it correctly, for my cloning to work, I would have to newly install LM13KDE from the bootable installation ISO to my new disk (just to have the disk properly partinioned, prepared and made duly bootable) and next restore my image on the second partion (as primary, or logical? - probably logical as the boot data would already be there... - but I may be wrong). Would this work? And would it also work if the new "second" partition would be of different size (obviously not smaller than the size of data on the image)? If all this has been done, would it work normally?
