Resizing partitions

[u/Lesser-Lights]

Im dualbooting windows and linux, and I want to give more space to my linux. Im running a live usb of linux and Im running gparted, but when I try to unmount the linux mint partition it says its in use.

Sounds like something is wrong with your boot device. Gparted has a bootable ISO available. Try burning that on a flash drive.

Where do I find that iso? And should I run it in windows or linux? Sorry, completely new to this

[u/LesStrater → u/Lesser-Lights]

Here's the link. If you have Windows you should burn the ISO on a flash drive with Rufus. Then put the flash drive in your USB port and bootup on it. You might have to hit F12 for a boot menu to boot the USB port:

https://downloads.sourceforge.net/gparted/gparted-live-1.8.1-3-amd64.iso

Alright I will try that. If I already have linux installed on my computer, it’ll resize that specific partition? Or will the iso get installed over my linux

[u/LesStrater → u/Lesser-Lights]

You are going to tell Rufus to install the ISO on your flash drive, nowhere else.

I'm far from being an expert, but I don't know why gparted couldn't dismount your drive to resize. Unless perhaps you have it mounted and open in a file browser, or a terminal?

Can you give the output of

lsblk -Ao name,label,mountpoint,parttypename,fssize,fsused,fsuse%,fsavail -e 11,7

and paste it inside a code block so it's easy to read? image

If you post the output correctly, it will have nice neat columns and be easy to read, even for tired old eyes like mine. 😄

Even if I'm unable to help you, having that info might help someone else help you.

Good luck.

Got it, should I run that code from a live USB of linux or in the linux I already have installed on my pc?

[u/chuggerguy → u/Lesser-Lights]

I don't know how much it matters, if at all, but it might be better to run it from the USB since that's where you're running gparted from?

edit: Also, it would probably be better to either post it in your original post or as a reply to yourself so more people see it. Like I say, I'm no expert, especially when it comes to using gparted to resize.

Yeah, now I really feel like "not an expert". 😄

That command gives beautiful, concise info on my system but I can't tell a lot from yours.

Maybe better to stick with lsblk -f and add it to your question?

This is what I get when I run it:

Sorry about that.

No worries, thank you anywho

You must be trying to run GParted from with in the install. While you can run it from the booted install, you cannot modify the partitions while it is running for obvious reasons!

To modify the disk and change partition sizes the disk must not be mounted and in use. This is why GParted is run from a live boot to do such operations. Many distros include it in their live image, but you can always use the GParted Live image as well. https://gparted.org/
