Unable to add free space to root partition

rated 0 times [ 2] [ 0] / answers: 1 / hits: 465 / 3 Years ago, wed, may 5, 2021, 8:17:32

I had a problem with the system not booting on a dual-boot (Windows 10 + Ubuntu) machine, which seems to stem from depleting all available space for the OS. I tried to follow a guide on YouTube on freeing some space from the D drive on windows, and then converting it to 'ext4' format to increase my root partition.

But, after reaching this last step, I am not able to increase the space of the root partition. I do not know why exactly, as this problem is at the limits of my technical abilities. I looked through questions here and on the internet, and I didn't find this particular problem.

One thing I noticed is that guides which talk about dual-boot systems talk about primary and secondary partitions, but I have no idea what that means.

Make sure that you have a good backup of your important Ubuntu files, as this procedure can corrupt or lose data.

Keep these things in mind:

always start the entire procedure with issuing a swapoff on any mounted swap partitions, and end the entire procedure with issuing a swapon on that same swap partition

a move is done by pointing the mouse pointer at the center of a partition and dragging it left/right with the hand cursor

a resize is done by dragging the left/right side of a partition to the left/right with the directional arrow cursor

if any partition can't be moved/resized graphically, you may have to manually enter the specific required numeric data (don't do this unless I instruct you to)

you begin any move/resize by right-clicking on the partition in the lower pane of the main window, and selecting the desired action from the popup menu, then finishing that action in the new move/resize window

Do the following...

Note: if the procedure doesn't work exactly as I outline, STOP immediately and DO NOT continue.

Note: "I want to add sda9 to sda8" won't give enough room to Ubuntu.

boot to Windows

copy/move files from /dev/sda6 (D:?) to /dev/sda5 (C:?)

delete the /dev/sda6 (D:?) partition using Window's Disk Management app

boot to a Ubuntu Live DVD/USB, in “Try Ubuntu” mode

start gparted

if /dev/sda9 is truly empty, delete the /dev/sda9 partition

move the /dev/sda8 partition all the way left

resize the right side of /dev/sda8 partition all the way right

click the Apply icon
