I have removed windows 8.1 from dual boot Ubuntu 14.04 following this tutorial . I used the OS uninstaller as described in that tutorial. But still when i boot PC, I see that windows has not been removed, it still works well, although OS uninstaller confirmed that windows has been removed.

What should I do to fully remove windows?

  • Do you mean even after uninstalling windows from the system, when you select windows from boot menu, you are able to log into windows ?

    in Ubutnu, Open Gparted and check, if your windows partition ( that you deleted) is still available and formatted as NTFS. I doubt windows partition was not deleted when you tried to remove it

You can try this tutorial found at lifehacker at Lifehacker.

1) Insert a live CD or USB for your Linux distribution and start up its partition manager (like Gparted). Find your Windows partition in Gparted's menu—it'll be listed as an NTFS drive.

2) Right-click on that Windows partition and choose "Delete" from the menu. Your machine may have other Windows-related partitions as well, like "System Reserved" and recovery partitions. If you want, you can delete these as well (but make sure you have recovery discs handy if you're going to delete a recovery partition).

3) Right-click on your Linux partition and choose "Resize/Move." Resize it so it takes up the rest of the now-free space on your drive.

4) Click the "Apply All Operations" button in the toolbar to perform the selected tasks. It may give you a warning saying that your computer may not boot, but with most Linux instalations this shouldn't be a problem (though if it is, check out this article to fix it). This process may take some time, so let it be!

When it finishes, you should have a hard drive with nothing but Linux on it. Your boot menu will still have some Windows entries, and it'll work fine if you leave them there, but if you want to clean things up, just open up a Terminal in Linux and run:

sudo update-grub

to remove them.

  • You can try deleting partition containing windows using gparted from your Ubuntu installation.

  • partho, you should be able to skip over the live cd/usb part of the process.
