I want to change the name of my partition so that I can change the directory from the terminal using the changed name. The current path to the partition is /mnt/8C5442D35442C026 which is long and I cannot remember it. I tried to change the path using GParted, also tried renaming the partition (or rather its bookmark) but to no avail.

How can I achieve it? I am running Ubuntu 18.10 along with Windows 10. I want to be able to use that drive/partition on Windows as well.

Edit:

The output of cat /etc/fstab is

# /etc/fstab: static file system information.

#

# Use 'blkid' to print the universally unique identifier for a

# device; this may be used with UUID= as a more robust way to name devices

# that works even if disks are added and removed. See fstab(5).

#

# <file system> <mount point>   <type>  <options>       <dump>  <pass>

# / was on /dev/sda5 during installation

You don't need to change the label, only the mountpoint. First, run sudo nano /etc/fstab and change this line:

/dev/disk/by-uuid/8C5442D35442C026 /mnt/8C5442D35442C026 auto nosuid,nodev,nofail,x-gvfs-show 0 0

To this:

/dev/disk/by-uuid/8C5442D35442C026 /mnt/myDisk auto nosuid,nodev,nofail,x-gvfs-show 0 0

Of course, you can change myDisk to whatever name you want. Then, create the directory:

sudo mkdir /mnt/myDisk

Next, either reboot or just unmount the partition and mount it again:

sudo umount /mnt/8C5442D35442C026

sudo mount /mnt/myDisk

Alternatively, you could always simply create a symlink pointing to the existing mountpoint:

ln -s /mnt/8C5442D35442C026 $HOME/myDisk

Now, you have the directory $HOME/myDisk and you can use that instead of /mnt/8C5442D35442C026.
