From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

what you are saying is: copy all your data to another drive, expand the boot partition shrinking the main storage drive and then copying back?
More or less yes, minus the copying files back if the operation was successful. You must be careful shrinking partitions as it is very easy to destroy them, and I'd have to guess the partition layout looks vaguely (EFI System Partition (
/boot/efi
), Boot (/boot
), Root (/
), ...), which would require shrink and move of the partition before or after/boot
. If you're unfamiliar with shrinking a partition, a bit of reading into how it is done for your filesystem will be required. Different setups, ext4, btrfs, lvm, LUKS, etc. will have different requirements.Use Gparted boot disk. It's a nice GUI program. It can resize partitions on the fly with data on them. It will move data within a partition if needed. I have successfully used it on XFS and BTRFS, YMMV. The usual advice of backup anything important is valid.
Although it's a bit dated, so I don't think it supports luks in the GUI. You might have to use it as a visual reference and do it via the command line.
is gparted better than KDE partition manager? or gnome's?
Haven't used those but probably pretty similar.
