Question

linux

It is necessary to transfer free memory from one disk to another disk. By what means can this be done?
I have two partitions, one with Ubuntu, the other with Linux mint, the one that is not needed with Ubuntu, I want to transfer free space from Ubuntu to the disk on which linux mint is.

Answer 1

Download a Linux live image (for example, www.system-rescue-cd.org/Download ), burn it to a flash drive, boot from it, and use the gparted program to delete the unnecessary partition and add the freed space to the remaining partition.
