sudo cryptsetup luksOpen /dev/sda1 dowolna_nazwa
sudo mkdir /media/my_device
sudo mount /dev/mapper/dowolna_nazwa /media/my_device
sudo umount /media/my_device
sudo cryptsetup luksClose dowolna_nazwa
To automatically put it in the /media location, use the udisks tool

sudo udisks --mount /dev/mapper/my_encrypted_volume

Windows 10 dual boot

http://askubuntu.com/questions/244261/how-do-i-get-my-hp-laptop-to-boot-into-grub-from-my-new-efi-file

This is what I did:

• I booted into my Ubuntu installation using the trick of the F9 key in the start up to be able to choose the boot loader.
• Once in Ubuntu, I opened a terminal.
• Using the command below, I checked where Windows boot loader was located:

  $ sudo efibootmgr -v
  

• In my case, the original boot loader was in here: /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi . Please note that in your computer it might be in a different place. If so, you will need to adjust the commands below.
• As per Rod’s recommendation in his answer (the one about how to repair the boot loader manually), I made a backup of that file by moving it one level down:

  $ sudo cp /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi /boot/efi/EFI/Microsoft/bootmgfw.efi
  

• Finally, I copied GRUB2′s boot loader in that place, “tricking” the system into loading the boot loader I wanted instead of Windows’ original boot loader.

  $ sudo cp /boot/efi/EFI/ubuntu/grubx64.efi /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi
  

So finally I had my dual boot working with GRUB2. In case Windows overwrites the boot loader again after an update (as it did with me), I already know the steps to get grub back to its place.
