I have had a few very kind people try to help me get basic, simple things done in Kubuntu 25.10, but not one thing is even working right. There is something very wrong.
How can I uninstall this Kubuntu 25.10, without the system blocking me, so I can re-install it and see if it fixes the glitz or what ever is stopping it from working right.
Thank you in advance.
We cannot uninstall Kubuntu or any of the other flavours of Ubuntu. The same applies to Ubuntu itself.
What we can do is install Kubuntu into the partition that is being used by Kubuntu. That will overwrite all the data in the partition. So, backup any data that you have created and do not want to lose.
Do you know how to do this? How did you install Kubuntu in thhis first place? Erase disk and install? Install along side? Manual?
I basically fumbled along installing Ubuntu. I had another âflavoursâ before and canât recall itâs name. What has become very apparent is that this is NOT an easy program and very finicky. Yes, I did erase all of Windows 11 and install it on my Dell Vostro. I sure wish I hadnât gotten rid of 11. As it is, I am very tired of fighting this program and am in the process of installing Windows 11 again, but this âwonderfulâ flavour keeps blocking me. I donât have any IT experience and am totally exhausted in working with Ubuntu. If Ubuntu is so preditorial that you canât uninstall it, it is not the right thing for me. But I will get it off my machine some how.
Thank you so much for trying to help me. Maybe some day later I will try again, but I canât even print a document from Kubuntu. Not even if I save it as a document. Something is very wrong.
What would be very nice is if you could tell me how to download Windows 11 onto a USB plug.
I just remembered that I actually had to take my computer to an IT guy and have him install Kubuntu. I guess that was a waist of $130.
The problem here is that we have no idea what he actually did.
Perhaps the issues you have been facing are a result of some misconfiguration or lack of knowledge of how to set up Kubuntu with defaults.
Or perhaps they configured things but not in a way that would make it easy for you to use afterwards.
We just donât know.
We are not in your shoes but my advice would be not to give upâŠyet.
You took the brave step of moving away from Windows and trying something else so perhaps you are willing to also try installing Linux on your own with some guidance.
If it were me, I would sleep on it (of course, I am taking a guess you are somewhere in the U.S. where it is daytime but for me it is late night already).
How did you uninstall Windows 11? I do not think you uninstalled Windows 11. I do not know of any computer operating system that gives the user an option to uninstall. We can, if we have the authority, install and uninstall (delete) programs/applications. But not operating systems.
I do not know how you do this from whatever flavour of Ubuntu you are using but here is how you do it from Ubuntu
Offical Install Ubuntu Desktop Guide
Go to the heading Download a Ubuntu image. That will give you clues how to download and install some other operating system who shall be nameless.
Of course, you could go to the web site of the nameless operating system and read its tutorials.
I have taken a vow to only give advice on using Ubuntu and its flavours.
P.S. This reply should have been posted minutes earlier. I had internet problems that I eventually solved by switching the router/hub off and on. We all end up frustrated sometimes.

I am in Idaho. It is 3.12 right now.
So, can you tell me what the advantages are for me to keep trying to make Ubuntu work for me? Because right now, nothing works. Everything I try to do is just stopped. The printer used to work. I had to send the print command 2 or 3 times, but it would work. And now I canât even print out some important papers. When everything you try to do is stopped, of course a person will get frustrated. If you say you can help me install Linux the right way, I am interested in that, of course. I am in Mountain time USA. I wonât give up if something pertinent can move my situation forward. But right now, Iâd just like to punch the computer. I have to work for a while tomorrow, but maybe I can chat with you in the morning. I just want my computer to work. Windows does just work.
I swear the devil helped invent the computer.
All I know is that at the start up, when I had Windows running, you could push the F12 button or one of them to enter a deeper section that allowed you to navigate the operating system, or delete certain things or change behaviors. A lot of my every day âthingsâ are fighting me so Iâm not real focused on any one of them, but I do need my computer working right. Seems like everything about life revolves around them now days. Hell, I just went and bought a bottle of sour mash to help me calm downâŠ. : ) Itâs very interesting getting to know how things work around here. Iâm a little confused as to why you canât mention the other guys. I guess if I kinda knew the big picture, I might understand more. The main problem I am having now, is that Kubuntu will not entertain anything about Windows 11 install⊠there again, I am stopped. Like Rubi1200 said, maybe the IT guy didnât install the program right, although he works at a very successful computer company here in Pocatello. I will try to read up on the link you gave me, but for now, I need a brake from this whole thing.
These descriptions are much too vague to offer any useful advice.
If my chainsaw isnât working, I can describe the problem to my mechanic. âThe chain is making a rattling noise on the bar.â Iâm not a professional in the logging industry, but any human capable of turning on the machine can tell us what they experience. They can write down error messages. They can take photos of their screen. They can focus on a single problem per topic.
Everybody you have encountered here is a volunteer. A fellow user. Most of us donât have âIT experience.â But we know a lot about how these systems work.
If you really want help, then put down the sour mash and start providing details about the experience that âI am stoppedâ is referring to.
Advice: Dial back on the grousing. It chases away highly-skilled volunteers who might otherwise be willing to help.
Maybe you didnât get the drift of what I was chatting about. 2 or 3 others did who are attempting to help me figure things out. The whole install is not working like a computer should. It may be because I had and IT guy install Kubuntu for me. When I get the time, the guys who actually chatted with me and understand what is going on are going to help me. Sorry if I am frustrated. This OS has not worked right since I had it installed.
If I get a couple more posts like yours, I will just go back to Windows. And if you are assuming that I am drinking and getting pissed, you donât know anything about me. That is a sorry statement about the sour mash. The OS is not working right. Other folks will help me.
I when I say it stops me, it means that the actions that I am trying to take, like simply printing a document, is stopped from performing that action. The program stops me from performing any type of actions that a computer is supposed to do. A lot of the times it says that the computer can not perform that action.
@idahobronco I understand your frustration. Spending $130 and ending up with a system that doesnât work the way you expected can be really frustrating, especially if youâre not very familiar with Linux yet.
Linux isnât actually blocking you. The operating system simply occupies the disk partitions, so there isnât an âUninstallâ button like a normal application.
To reinstall Windows 11, you need to create a Windows installation USB using another Windows PC. After that, boot from the USB and choose Custom Install. Then delete the existing Linux partitions (including those created by Kubuntu).
Once those partitions are removed, the Windows installer will recreate the necessary partitions and install Windows normally.
I feel for you re your frustration with computers. After a nights sleep I think you have two options but be aware of a number of things. PCs purchased with Windows on often have been âtweakedâ by the manufacturer to get their hardware to work efficiently with Windows. Once they have done this they can churn out the PCs in their thousands. This is why on most manufactures sites you can download specific Windows drivers for their machine. Even when you do this (Iâve done this many times) there are times when you still need to do some âfiddlingâ. The same, I would argue to a lesser degree, is the same with Ubuntu (obviously it depends on the specific pc you have).
If you go down the route of re-installing Windows you basically save any personal data, wipe the machine and rebuild. The same as you would installing Ubuntu. Both methods involve downloading the OS from the Windows or Ubuntu site, installing it on a usb stick and then installing it on your pc.
There are many forums sites to help you but as ian-weisser alluded to - this is an excellent site for help. If you go down the Ubuntu route volunteers here will guide you through the whole process in precise detail - even with systems that have both Windows and Ubuntu installed (called dual booting).
My advice (having been a long time Windows user but now converted to Ubuntu for the last âdecade and bitâ would be to install Ubuntu 24.04 (not kubuntu) which is a long term stable release - a move you will not regret.
Installing Window 11 again is an option and nothing wrong in that as it is a good OS. But as you have come to a Ubuntu forum you are bound to get a âUbuntu Slantâ as most, if not all of us, have originated from Windows and now enjoy the benefits of Ubuntu.
Ian-weisser is correct in that if you ask for help here (and you will get it) you are going to be asked for quite detailed questions on your hardware.
In terms of needing a working PC asap (you mentioned needing it for work) installing the Ubuntu on a usb stick will allow you work off that usb and have a fully working system*. This avenue may or may not be relevant for you. Believe me, if you need a âpcâ asap this is far quicker to achieve than going down the fully loading Windows route. (I.e. you need access to email or to âwebâ something)
I understand the suggestions about trying different Ubuntu versions or using a Live USB. Those can definitely be useful in many situations.
However, since the original post mentioned needing a working PC for work as soon as possible and already had a frustrating experience after paying for the installation, the fastest path back to a stable system might simply be reinstalling Windows 11.
That doesnât mean Ubuntu is bad â it just means sometimes the priority is getting a reliable environment quickly. If they want to try Linux again later, they can always revisit Ubuntu or another distro once things are less urgent.
Nothing is working on the Kubuntu you installed, youâre in the process of reinstalling Windows 11 (which is automatically erasing any other OS) and you donât know how to uninstall Kubuntu, while also remembering that you gave your Dell Vostro to an IT guy that you paid to install Kubuntu.
Understood.
Ubuntu 26.04 is in Beta now. Could give that a go
I understand your frustration. Hereâs how to completely remove Kubuntu 25.10 and reinstall properly.
Kubuntu 25.10 was released in October 2025 and is supported until July 2026. If basic things arenât working, it might be due to stability issues with this non-LTS release or a bad installation.
Step-by-step to wipe and reinstall:
1. Create a bootable USB with Kubuntu 25.10 (or the more stable 24.04 LTS) using Rufus (Windows) or dd (Linux/macOS).
2. Boot from that USB and select âTry or install Kubuntuâ .
3. Open GParted (partition editor). Locate the drive where your broken Kubuntu 25.10 is installed and delete all its partitions (typically ext4, /boot, swap, etc.).
Be careful not to delete Windows or other important data partitions.
4. Run the installer from the live USB. Then choose manual partitioning and install Kubuntu back into that free space.
5. (Optional) Clean up old boot entries from BIOS/UEFI settings or using efibootmgr.
Thank you for understanding. It has been very frustrating. It works just enough so that I can use basic apps and programs but there is obviously something wrong. I got into the deeper computer set up by using the F12 button and found the links for Windows10pro re-install. I am going to run it side by side with Kubuntu, OR can you offer advise to a better flavour or option of Ubuntu? And what Kubuntu is doing is not allowing me to perform actions, like a simple copy of a document. It used to work, after I pushed the print button 2 or 3 times which means it wasnât working right in the first place. rubi1200 has identified that maybe the IT guy didnât install the program right in the first place, which I am now believing to be true since so many aspects of it do not perform right.
Like I say, the core of the computer had the links to reinstall Windows and repair it, which I have done most of, but it wants me to back up all my files, which either I donât know how to do with Kubuntu OR it is not letting me do it.
Also, I donât understand the disk partitions or partitions in particular. Donât know if that is part of the Linux language, such as flavour means different forms of Linux programs, or if it is something that I have never been exposed to. Once I understand the language I will understand everything better.
Again, thank you for understanding. I appreciate any and all your help.
This is very nice to hear from prior Windows users who have experienced different things. I appreciate your advise. I will go for just the Ubuntu 24.04 when I get back to that. Before I was doing everything blind, thank you for the assistance.
I have a better understanding of how a computer bought with Windows would have safe guards to protect its software. That makes sense. Is there PCs that come with Ubuntu installed?
Where I am at now is that I have reloaded the original Windows 10 pro, but they want me to save all my files and documents before the actual install. I donât know if I just donât know how to do that in Kubuntu or if something is conflicting with my commands. Ultimately, what I want to do is reinstall the Windows program and then have the Ubuntu 24.04 installed as a dual boot. It offered to do that back when I initially installed Linux but I didnât know how to do that.
So I have the Windows ready to install, I just need to backup my files. Once all that is done I will install Ubuntu again. Thank you for pointing that out. I truly do want the best flavour of Linux. I have a formatted exterior hard drive attached to the computer waiting for the back up, I guess I need to know the proper way to perform that action. What gets me is that when I go to do something like that a window pops up that asks which program I want to use, and I donât know the proper programs to use. I think that is where Windows is different. It seems to just have default programs that automatically run when a task is trying to be performed.
I have given up on the immediate need of my pics and documents. If I can get this computer working within a few days, I should be fine. My peice of mind and lack of stress is more important right at the moments.
My most demanding task is to get my files backed up onto my external hard drive. Can you guide me through that? Again, itâs the pop up window with the âwhich program do you want to useâ that completely confuses me. I wish they were listed as the best ones first, but there are so many of them. I have to go to work for a couple hours, which sucks because it is Sunday, but I will be back in 4 hours or so.
Like I say, I have the Windows thing handled, just need to back up my files and install it. Then I will reinstall the Ubuntu as a dual boot, with you good folks help. I really appreciate you all.
