I have faced a problem when trying to install ubuntu 14.04 version on my windows 7 os by wubi. It say permission denied and refer to the specific folder on drive C (I make a directory of wubi and ISO file in drive D). I failed several times while i was installing it.

I try to solve it by

  1. disable my adaptor
  2. make wubi.exe in the same directory with Desktop ubuntu. ISO file
  3. click run wubi.exe


it say "Can't download metafile and therefore ISO"


  1. click wubi.exe to download file again by bit torrent
  2. wait for 2 hours at the last minute, it say "permission denied.. bar bar and show me the path"

How could i do or solve it, please help me....


Wubi is no longer supported. See this link

Ubuntu Forums Staff recommendations on WUBI

Though WUBI (Windows-Based-Ubuntu-Installer) is included with the Ubuntu ISO up to the 14.04 release it is no longer officially supported by Canonical.

With no active development for Wubi, there are few experienced users of Ubuntu who also use wubi on this forum, and hence few here who can give informed support for wubi.

There are some existing resources available for those who choose to use this application as a means to try Ubuntu.




I recommend that you download Ubuntu 12.04.5 iso image or Xubuntu 12.04.5 or Kubuntu 12.04.5, your choice, and also download the executable, wubi.exe from the same page. Place both files in the same folder and install Ubuntu with wubi.exe, no Internet connection or additional download needed. If possible, choose another partition to install Ubuntu instead of the partition where Windows 7 is installed.

It is better this way because you will be able to use all the software that no longer work in Ubuntu 14.04.

And if you really need to make wubi.exe work with Ubuntu 14.04 you have to use a simple command after first reboot, that is after you started wubi installation in Windows and it asked you to reboot the system to continue installing Ubuntu 14.04. Basically, you have to press the key e at first boot prompt for Ubuntu and look for this line to edit it:

         linux  /boot/vmlinuz-3.2.0-68-generic root=UUID=B21CF9B91CF978A5 loop=/ubuntu/disks/root.disk ro

and replace it with

          linux /boot/vmlinuz-3.2.0-68-generic root=UUID=B21CF9B91CF978A5 loop=/ubuntu/disks/root.disk rw

As you can see, all that is needed is to change ro to rw after section loop=/ubuntu/disks/root.disk from that line. Next, you can press F10 to boot and hopefully, this way, Wubi will finish installing Ubuntu, but after you get there and find yourself facing your new Ubuntu desktop, you should edit the same line(s) in grub.cfg, a file which is located in ~/boot/grub/grub.cfg. To edit grub.cfg use this code in a terminal window:

     gksu leafpad /boot/grub/grub.cfg


     sudo nano /boot/grub/grub.cfg

and look for the same line:

   linux    /boot/vmlinuz-3.2.0-68-generic root=UUID=B21CF9B91CF978A5 loop=/ubuntu/disks/root.disk ro

and also for this line:

   linux    /boot/vmlinuz-3.2.0-68-generic root=UUID=B21CF9B91CF978A5 loop=/ubuntu/disks/root.disk ro recovery nomodeset

and replace ro with rw so they look like this:

         linux  /boot/vmlinuz-3.2.0-68-generic root=UUID=B21CF9B91CF978A5 loop=/ubuntu/disks/root.disk rw


          linux /boot/vmlinuz-3.2.0-68-generic root=UUID=B21CF9B91CF978A5 loop=/ubuntu/disks/root.disk rw recovery nomodeset

Once again, all you have to do is to change ro to rw after this section loop=/ubuntu/disks/root.disk so you stop experiencing problems each time when trying to boot into Ubuntu.

You can use this solution or you can simply press e at each boot prompt for Ubuntu and edit that line and change RO to RW every time you want to use Ubuntu. This is a very useful command since you'll be forced to upgrade your system to yet another kernel version (Update Manager will take care of that...), and after that you'll have to edit file grub.cfg again because of the new kernel and replace ro with rw again in grub.cfg.
