I am doing encrypted disk installation. First partition is /dev/sda1, mount point is /boot and it is unencrypted and second partition /dev/sda2, mount point / and it is encrypted partition. Whole installation went fine but stuck at Install the GRUB boot loader on a hard disk. It's not going anywhere from here. No movement in progress bar.

Update:
I have just tried to install without any disk encryption and it is stucked again on same step.
