I tried installing ubuntu 12.04 32-bit along side windows 8, and I encountered an error. I determined that I need to install the 64-bit version instead. I need to delete the old directory containing the files associated with the old ubuntu installation. How can I do that?

  1. Boot into LiveCD of Ubuntu
  2. Install gparted
    • sudo apt-get install gparted
  3. Run gparted
  4. Select the HDD containing your Ubuntu installation
  5. Be very careful to select the partition containing your Ubuntu installation.
  6. Check again that this is not your Windows partition
  7. Delete said partition (there may be more than one, depending on your setup)
  8. Begin installation of Ubuntu on newly available freespace.

Just format the partition with Ubuntu on, and install the 64bit one. You can do it from the installer.

Windows 8 will not allow me to do that. I insert the liveCD to the drive, and attempted to run wubi.exe from Windows 8, but it simply stops and says there's already a directory named Ubuntu and won't move forward. I also tried restarting the computer with the liveCD in the optical drive, but my computer simply starts up windows 8. How can I get around this? – DivDiff Jun 26 '13 at 2:23
Dont use Wubi on a Win8 PC... Install from the LiveCD after booting from it. Hit F10 or F12 when you start the computer for a boot menu. Or hit F2/Del to get into "BIOS" settings to change boot settings... – aXept Jun 26 '13 at 3:32
