 **EN:** A script to extract a data image via the  **[ntfsclone](https://linux.die.net/man/8/ntfsclone)** utility from XEN \ KVM media<br>
 Parameters for using the script are specified in section **manual_parameters**<br>
-for the script you need the package **dialog**.

+to get the necessary parameters of the script - an example:<br>
+```
+losetup /dev/loop1 /kvm/win7x64/disk_c.img
+losetup -a
+dev/loop0: [2055]:2103175 (/kvm/win7x64/disk_c.img)
+```
+
+`fdisk -l /dev/loop0`
+
+```
+Disk /dev/loop0: 80 GiB, 85899345920 bytes, 167772160 sectors
+Units: sectors of 1 * 512 = 512 bytes
+Sector size (logical/physical): 512 bytes / 512 bytes
+I/O size (minimum/optimal): 512 bytes / 512 bytes
+Disklabel type: dos
+Disk identifier: 0x677d5646

+at us on an image of 2 sections.<br>
+each partition is: sda1 and sda2<br>
+the offset for each section is obtained by computing:<br>
+
+**sda1 offset :( 512 x 2048 = 1048576)**<br>
+**sda2 offset :( 512 x 206848 = 105906176)**<br>
+
+the result is added to the section of the script manual_parameters<br>
+Now the script itself can both save and restore data from the virtual machine image.<br>
+**Attention!!**<br>
+**Before using the script, I recommend that you first make a copy of the image file (example: /kvm/win7x64/disk_c.img)**<br>
+and only if everything went well, a copy can be deleted.<br>
+The script dialog supports 2 languages: RU and EN<br>
