How do I remove Unbuntu 11.10 that was installed through Windows?


I am an absolute newbie with Linux. I installed Unbuntu 11.10 from within Windows. I would like to uninstall Unbuntu and reinstall it in its own partition. How do I uninstall unbuntu - it does not seem to have any uninstall features showing?

Hi,

1. If it was installed from within windows, you could find it in the add/remove programs within control panel.

If not boot into windows and then run the ubuntu installation cd, go further with it. The installer will

see the ubuntu installation and ask you to whether to repair, clean install or uninstall the existing

installation. Choose to uninstall at this point.

2. You could also keep the existing installation and install it as a separate OS provide you have enough free

space for ubuntu to use.

Please check and revert.

Regards...

The other option can be to remove linux partitions from windows. Right click on My Computer, click Manage. Choose Disk Management listed under Storage and you will see all of your partitions listed there. From there you can delete linux partition. After rebooting the system you'll notice that the grub has gone and you'll not be able to boot into windows. Now you would need to boot from windows CD to restore the MBR. Boot the system from windows CD and choose to repair the system, you'll be droped into comand promt. At that point run the two commands fixmbr and fixboot. If you run fixmbr only it will also work fine. Now when you reboot your system everyting would be fixed and then you can choose to install Ubuntu freshly.

If Ubuntu is installed from within Windows (read: using the Wubi installer) then it is installed into a container file, not its own partition. Also, fixmbr and fixboot are for Windows XP only. Newer versions use bootrec.exe with the /fixboot and /fixmbr options.

Use add/remove application from your control panel in windows. It should show there as WUBI or as Ubuntu I dont know exacly.
Good luck to you

Initially Ubuntu did not show up in the add/remove programs list. And I had no installation CD for Windows, my computer came with a recovery partition.
I deleted the C:/Ubuntu folder and then re-installed Ubuntu with Wubi. It now appears in the add/remove list so all is well.

Thank you all for your help.

What size partition would you recommend for Ubuntu?

Depends on how much you want to install, this is my Ubuntu install:
Code:
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda1              3890452   2589672   1103148  71% /
It is just a 4BG partition, if you plan to install lots of programs then it would be good idea to start with 15GB or more just for the root(/) partition, it is also good idea to have separated partition for /home which can be even bigger and used for storage(music, video, etc). Now for a more advance installation if you have more than one hard drive the home partition could be alone in a second hard drive.

Regards

If you're installing Ubuntu Desktop Edition then you need atleast 15GB free disk space, if you're going for Ubuntu server CLI installation then minimum requirement is of only 1GB. Lightweight GUI alternative like Xubuntu and Lubuntu is also there which require atleast 5GB of free disk space. And if it is netbook edition then 4GB of free disk space is required.
These are all minimum disk space requirement, now choice is yours.

I'd say if you have the room in your hard drive allow 20GB or more 40GB, 80GB. The thing is that as you become familiar with the new OS you will want to add more applications.

Make sure you create a Recovery Disk for Windows, and Back up all your important files just in case before you make any changes to your system.

Good luck to you!
