The image describes the current HD on my laptop. Its a dual booting system with Linux Mint - primary OS, and a backup Windows 7 (rarely used, but required.)
While creating the ext4 partition I made a mistake and allotted only 12GB. This is now becoming a bottleneck, I have to frequently move many installation folders and symlink to the ntfs partition.
I want to increase the 12GB ext4 to maybe 20GB --- meaning the /dev/sda2 (ntfs) will reduce in size and ext4 will increase in size.
What's the safest way to do it without screwing up the existing installation?
/dev/sda2
and expand/dev/sda3
after cloning your disk and use an application such as R-Studio Disk Manager.
