Uninstall ubuntu to install Windows

[psyket]

Hi!
I installed Linux since I really enjoy the OS, alot more fun than Windows, but the problem is that I cant play any game when I'm bored. So I'm going to install Windows and then install Linux alongside again,

But to do that I need to uninstall Ubuntu, so my question is, how do I do that?
I tried to just boot from the Windows CD, but after a while it says that it cant proceed caused by an error that says that my CD/DVD-Rom or my USB is failing or that is isin't connected, cant really remember. But my DVD-rom works perfectly when not running the Windows-CD.

Is this problem caused by that my HDD got EXT4 instead of NTFS?

Thanks in advance for any help!

Hello and Welcome.
Yes, that could very well be your problem. You can follow these instructions for removing Linux.

Thanks for the reply!
A friend linked me the exact same homepage earlier, how do i get into the command prompt?
And this "fdisk" is it the CD I installed Linux from? If so, how do I use it to delete the partitions, I tried to uninstall from there earlier but without any progress.

Welcome aboard!

Just boot up to the LiveCD.
You can locate the terminal from your Applications menu, Accessories.
Then just follow the steps in the link that Mike provided.

If you have any issues, please post back with as much info as possible.

I'm a bit confused here, what exactly should I do? Restart the computer with the CD I got Linux on and then?
Or should I just go to the terminal now and follow the steps?

Restart with your Ubuntu disc.
After booting up with it, you will have a working system that runs from the CD. This will allow you to safely follow the steps provided.

The computer wont boot up with the CD when I restart it, and when trying to get in to BIOS to change so that it does I just get in to the GRUB menu, any idea how I should do?

During the startup, you might see a message flash in the corner of your screen, something along the lines of: Press <F2> to enter setup.
The keystroke needed will depend on the actual computer model. Some folks need to hit <Esc> or <F11>...
try various keys and look for any type of message to flash.

The main problem were that I had an empty CD in the driver, I started up Ubuntu through the CD and opened up the terminal, entered "fdisk" and then tried to enter the other like "m" and so on, but there were no such command, am I doing it wrong?

I'm confused...
do you mean that you put a blank CD in the drive? And booted with it?
If so, that's the problem.
You need some form of LiveCD to boot from.
Do you still have the actual disc that you used to install Ubuntu? If so, use that.
If not, GParted might be the best option for you right now.
Download and burn a copy. It's main purpose is to handle disk partitioning.
