For the dual-boot I've allocated about 22 GB space from the disk. But actually, I'm having about only 10 GB space available for my own usage.
$fdisk -l shows me the following:
Disk /dev/sda: 223.6 GiB, 240057409536 bytes, 468862128 sectors
Units: sectors of 1 * 512 = 512 bytes

/dev/sda6 443926528 468860927 24934400 11.9G 82 Linux swap / Solaris
Partition 3 does not start on physical sector boundary.
I don't know much about this swap partition, but I really need to have more space on my linux.
Is there an option to take memory from the swap? How? What will be the consciouses?
