Uninstall Delete Ubuntu

So you only have Ubuntu and want to delete it ??

What do you want to do with your PC once ubuntu has been deleted ?

Install Windows

https://help.ubuntu.com/community/WindowsDualBoot

If you have the Windows disc then just rebooting with that will allow you to delete the Ubuntu partition. This will destroy your data tho so i recommend setting up a dual-boot system until you can get Windows working properly and then transfer your data back into Windows and then delete Ubuntu and expand Windows to fill the whole disc again.

Good luck with which ever way you choose.

I just want to erase my harddisk which has the Ubuntu OS

I tried to reboot on my windows CD but this resulted in blue screen before I got to delete the Ubuntu Partition

Using the Ubuntu live install cd please boot your pc from it and please test you RAM memory from the menu item...

Thank you

The blue screen sounds like the start of the Windows installer. It usually takes a while to get started. Was there any white writing on the bottom of the screen?

Yup, it is very possible that you have a hardware problem (as marcobra suggest), not a software one.
Can you explain a little more about the blue screen? because the normal xp installation starts with a blue screen, or you mean a BSOD? in that case, can you tell us which message do you have?
Hope this helps, let me know.

When you want to erase your complete disk and install just Windows. Insert the CD or DVD of Windows, boot on it and follow the on screen installation instruction. Note that the install of Windows XP might still be in text mode against a blue background.

This is a Windows problem. AminJensen is clearly unhappy with support in/about Linux issues and should try using Windows Support

Here is the problem status of now: I get to install the basics of windows and then it cuts to a bluescreen saying that it failed something that I don't recall completly but I think it was "CHDSK" Or something alike. and gives me the problem and it is a lot of 0's and ends with a 4 digit number or so. I can provide the full details if needed. Hope you can help.

When I say a bluescreen I mean an Error Screen when something failed. Sorry

If it was chkdsk, it means that Windows installer tried to check the partition for any mistakes before installing, but it could not. Probably because it is not a format supported by Windows (i-e a Linux format like ext3).
The solution is to choose during Windows installation to reformat all drives. But take great care as this will erase all data.

Note that as Tom mentioned it, this is not a Linux or Ubuntu issue. This is a bug in the installation of Windows. You will get better support by contacting the Windows communities (if that exist) or support. We are here Linux users, and although some of us need to deal with Windows from time to time, we are not expert with this operating system from Microsoft.

Thanks Huygens, that solved my question.

Thanks Huygens. This helped me a lot. I am going to consider this question solved(partially). But the problem occurs before I get the option to delete erase the harddisk. But maybe this is out of knowledge for Linux users

Thanks Huygens, that solved my question.

If you still have the Ubuntu Cd then you can use it as a boot-disc, choose the "Try Ubuntu wihout making any Changes to my hard-drive" option. I can't remember exactly what it says, something like that tho. When you get to the Ubuntu desktop go up to the top taskbar and click on

System - Administration - Partition Editor

When gparted starts up do a right click on the big blue partition and choose delete. This will wipe Ubuntu and all your data from the hard-drive. Then right-click on the red partition and choose "Swap Off" and then right-click it again and choose delete again. Now click on the "Apply" button. This should be enough to let Windows install.

Tom :)

PS this really goes against the grain with me as i know how tough it is to install Windows and a problem this early doesn't bode well. Another difficulty i have with this is that its tough for me to miss out on keeping data intact. But this is what you requested. I'd be happier if you asked how to keep all your pictures, documents and movies and such like.

If partition editor wasnt in that menu then go further down the Administrator sub-menu and click on Synaptics Package Manager and use one of the search tools to look for "gparted", install that by right clicking and then click "Apply" and then follow the instructions in my last post (ironic wording)

Thanks Tom :). This will help me a lot.

You're welcome :)

"E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
E: _cache->open() failed, please report." This happened when I followed your instructions, Tom. I went into the the Synaptics package manager. Can you help me?

When typing in dpkg --configure -a it said something in the ways of "Requires superuser rights to perform this action". It is translated from Danish. Might not be the exact same thing in English

The "dpkg --configure -a" is asked by the system when a previous update/upgrade process have not completely performed good, and it must run with "root" privileged administrative user.
Using the "sudo" command we can do a command as "root" user, and "dpkg --configure -a" need be run from root user.
After the "dpkg --configure -a" command i add all the usual commands (see below) you can run to be sure your system became fully upgraded.

So please be sure your system is fully updated/upgraded with no pending packages or errors:

Open a Terminal from the menu Applications → Accessories → Terminal and type:
(if the system ask you a password give your user password, you will not see nothing when you type it, then press enter)

sudo dpkg --configure -a
sudo apt-get -f install
sudo apt-get --fix-missing install
sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get clean
sudo apt-get autoremove

Hope this helps

I could go through that until it I said "apt-get --fix-missing install" Then my terminal froze and it began setting sun-java6-jre up. And it pops up with the License agreement in the terminal and a "button" in the bottom saying <Ok>. I can't seem to be able to press that though. I have tried waiting. I don't think it helps. Is it supposed to do that and if so, then what do I do to continue all the commands?

Press tab key and highlight the "ok" then press enter....

Hope this helps

Indeed it did. Thanks :)

Brilliant, nicely fixed :)

Welcome back :)))

Oh no. I meant Macobra. But that is a step towards completing this :)

How do start Gparted up? Embarrassing question maybe :)

My bad. Never mind. Found it

I still can't get it to work. I followed the instructions, but I still get the same CHKDSK error.
