Thanks for your answer but the problem is the loader stops before
loading GRUB itself so I cannot do anything within GRUB. The "GRUB "
text was displayed by boot sector of partition. This means that GRUB
loader in boot sector of partition does not find the next stage of
GRUB. I do not know why. I do not know how to reinstall GRUB to my
Debian partition. The UUID of swap partition lost in clone but I think
there is a myriad of tutorial how to change UUID of partition.

Here is the blkid output:

/dev/sda1: UUID="01CBD00909925860" TYPE="ntfs"
/dev/sda2: LABEL="rootfs" UUID="6fcb6e1c-92a2-4ac5-beac-e997ab08491f"
SEC_TYPE="ext2" TYPE="ext3"
/dev/sda3: TYPE="swap"

Here is the grub.cfg part:

menuentry 'Debian GNU/Linux, with Linux 3.2.0-3-amd64' --class debian
--class gnu-linux --class gnu --class os {
	insmod gzio
	insmod part_msdos
	insmod ext2
	set root='(hd1,msdos2)'
	search --no-floppy --fs-uuid --set=root 6fcb6e1c-92a2-4ac5-beac-e997ab08491f
	echo	'Loading Linux 3.2.0-3-amd64 ...'
	linux	/boot/vmlinuz-3.2.0-3-amd64
root=UUID=6fcb6e1c-92a2-4ac5-beac-e997ab08491f ro  quiet acpi=force
	echo	'Loading initial ramdisk ...'
	initrd	/boot/initrd.img-3.2.0-3-amd64
}

And here is the fstab:

# / was on /dev/sda2 during installation
UUID=6fcb6e1c-92a2-4ac5-beac-e997ab08491f /               ext3
errors=remount-ro 0       1
# swap was on /dev/sda3 during installation
UUID=d76a59a5-e778-41c6-8d2d-e10a52bd739f none            swap    sw
           0       0
