+Fix the new partition
+---------------------

+The new partition must be checked and fixed before resize.

+Fix it first in the host:

+Now we need to let the Windows virtual machine to check the drive.
+
+First of all disconnect the device from the *nbd* to let it run in the virtual machine.
+It is a good idea to remove the *nbd* module to make sure it is properly disconnected.

+.. prompt:: bash #
+
+  qemu-nbd -d /dev/nbd
+  rmmod nbd

+Boot the virtual machine, enter the *cmd* as admin and check the disk. This command
+will check the disk on the next reboot. Answer yes when asked and reboot the virtual
+machine. It will probaly warn you that the disk will be checked unless a key is pressed.
+Do not press any key, let it continue itself. In a few seconds it will be verified.

+  ntfsresize /dev/nbd1p2
+
+Disconnect again the nbd and start the virtual machine.

+.. prompt:: bash #

+Check the new size

+Boot the virtual machine again, go to storage properties of the PC. The new size
