We need to take out 2 GB space from the partition where Vista is located, which involves the adjustment of NTFS partition. You can use gparted to adjust the size of the NTFS partition where Vista is located. However, it is not good to use gparted to adjust the NTFS partition, this is mainly because the adjus

Introduction
Clonezilla is a good system cloning tool, which is capable of absorbing the advantages of Norton Ghost and partition image. That is, not only the whole system can be cloned, but also a single partition can be cloned. This flexibility may be more suitable for the needs of the backup.
If you have any requirements, please pay attention to the functions of clonezilla:

Int clone (INT (* fN) (void *), void * child_stack, int flags, void * Arg );
Here FN is the function pointer. We know the four elements of the process. This is the pointer to the program, which is the so-called "script ", child_stack obviously allocates system stack space for sub-processes (in Linux, the system stack space is 2 pages, that is, 8 KB of memory. In this memory, values are placed on the low add
