How to uninstall ubuntu??

Link to this post 19 Nov 09

In that case what you need to do to uninstall ubuntu is:
1. delete the ubuntu partition(s)
2. then boot up your window rescue/recovery disk/partition and go into recovery mode, once in recovery mode you need to run the command "fixmbr", that command will remove the ubuntu bootloader and reinstall the windows bootloader.

If you are looking for a quick fix then you can just overwrite the mbr now and then delete the partitions when you need the space.

If you install didn't even get far enough in the install process to add the bootloader, then all you need to do to remove it is delete the ubuntu partition(s).

If you are still seeing an ubuntu option after running the fixmbr command then that means that the entry is in the windows bootload, that is an effect of using the wubi installer. If it was indeed installed by wubi then you should bee entries on your C: drive that are called wubi* or ubuntu* that are your actual installation.

To completely remove a wubi installation you first need to delete the wubi and ubuntu files from your C drive, then you right click on the my computer icon, go to properties, click on the advanced tab, click on the Startup and Recovery settings button, under System Startup click Edit, and in the open boot.ini file you can remove the ubuntu option from the windows bootloader.

Now this thread is quite informative since I have covered the uninstallation of ubuntu from both a wubi and physical installation.

As always please respond with any additional questions or issues that you have.

Those files are the boot instructions, kernel image and the virtual disk(s) that hold your ubuntu installation. In the wubi installation the files are not written to a new partition, but are written to the virtual disk file(s) that are stored on your C: drive.

Now if the ubuntu physical partition was used then you may have installed two occurances through seperate install attempts, one as a physical install and the other as a wubi installation. Buy removing the files and the partition then you would be removing both installations of ubuntu and all data that resides within those installation.

You can safely remove all of the wubi and ubuntu files and remove the ubuntu boot entry. But by removing these files the ubuntu boot entry will not work and you will loose all access to your previous ubuntu installation.

Feel free to report back and ask questions when you are willing to allocate some time to fully installing and distro. Who knows, we may help you find some functions that will make you question ever going back to windows ;)
