I'v been searching around and learned that I can't just move unallocated space between partitions. I have to make it so it gets close to the partition I need to increase space. How can add this 50GB of free space to my root partition (dev/sda1)?
My unallocated space was inside the extended partition (I removed 50GB from /dev/sda5 and then removed it again from /dev/sda2).
PS: I was live booting.
