Hello all 
Ok, let’s go:
You need to RESIZE the partition, to do that:
DELETE the first partition, i/e “SYSTEM”, then resize (use the space before the main partition), and SAVE the changes;
Use BOOTICE to mark the partition active;
bcdboot and bcdedit to create the bcd rep. and set the flag on the partition;
Example:
Disk: 100GB
Target system: Windows 7
Schema:
P1 -> System, boot
Size -> 100MB
P2 -> Windows 7
Size -> 98GB
After resize, you got:
P1 - > Windows 7
Size -> 100GB
Then, bootice, mark as active, bcdboot and bootsect (create bcd repository / set the boot flag on partition).
Example: If you got 1 partition, aka “C:”, to the bcdboot command:
bcdboot.exe C:\Windows /s
/l en-us
Then
bootsect.exe /nt60 
and DONE
