Why don't I have this option?

here's my disk layout

sudo fdisk -l

The ubiquity installer offers to Install inside Windows when it cannot install alongside. i.e. when you already have 4 primary partitions used. This means that splitting the Windows partition is not possible.

If you select this option, it copies wubi.exe to the Windows Startup folder, so that when you next boot Windows it will automatically run Wubi.

Since you don't want to install with Wubi, you'll need instead to remove one of the primary partitions, and try installing again.

Here is an example of what ubiquity shows (although in this case the user has Windows XP, not Windows 7): enter image description here

  • Indeed, it seems to be I have 4 primary partions. That is the answer to my problem.

  • I guess you will have to use WUBI after all :)

  • @Ahmadgeo you don't have to use Wubi. You just need to remove one of the partitions. This is actually very common to have OEM-installed computers shipped with 4 partitions used.

  • @bcbc; The problem with OEM partitions is that they are either small in size, or are Recovery partitions so I -personally don't like to mess with :)

  • @Ahmadgeo right. I don't like it either. But if you want Ubuntu (and not with Wubi or a VM) then there's no choice.

There are several possibles causes:

  1. Your system already have 4 primary partitions:

    The solution is removing one.

  2. Windows wasn't shutdown correctly. You must make sure Windows shutdown, no hibernation, no suspend, but a clean shutdown.

  3. Your NTFS partition is dirty. You must check all your NTFS partitions for errors using:

    chkdsk /f c:

    For each partition, d:, e:, etc. Make sure you do this from Windows, not Linux.

  4. If you are using Windows 8, disable fast boot. If you don't is like you are hibernating the system.

  5. If Ubuntu installer reports an empty disk, it's more likely that you have leftover GPT data that needs to be removed.
  • I have two partitions. 50 and 200 gb. 50 gb partition is the system disc. I already tried to take small piece (20 gb) of 50 gb and format it in fat32, doesn't work. Also, I tried same thing with allocation space, doesn't work. Windows 7 is not recongnized. chkdsk /f c: live@live:~$ chkdsk /f c: chkdsk: command not found live@live:~$

  • @celavju no need. Just boot up windows, open the command line and type those commands.

    Another possibility is Intel Smart Respose. Also see askubuntu.com/questions/164980/…

In your windows system run a chkdsk on your disks for faults and relaunch Ubuntu installation.

And while you are in your windows system check your disks under Disk Manager (right click on Computer>Manage>Disk Manager) if it says that your disk is dynamic you wont be able to rezise them so the option of installing side by side cannot be handled by Ubuntu (is a Windows thing).

If you have a dynamic disk you have 2 options, format all and reinstall or use Microsft's own solution for converting dynamic disks back to basic. (note: ignore the title and body of that KB, go straight to the workaround). No warranties there!


The best thing is to backup your data and re-install Windows. When you are in the reformat drive screen you can choose to create new partitions. Always create at least 2/3 of the drive to be dedicated to the following:

[Windows XP][Free Space ---------------------------------------]

So you can create the following..

[Windows NTFS][-----------FAT32---for---storage----][Linux EXT4]

If you are using Windows 8, disable Secure UEFI boot. Also, it's a bit difficult. The new system doesn't allow installation alongside Win8 easily. Make sure boot mode is Legacy.

    If Secure Boot were a problem, the Ubuntu installer wouldn't boot up at all. Secure Boot does not cause a disk to appear to be empty once Linux is booted -- it causes Linux (or even GRUB) to not appear at all unless a Secure Boot tool like shim or PreLoader is installed. Booting the installer in Legacy mode will just cause problems on an EFI system, because then you'll have a mixed-mode (BIOS/EFI) installation, which is harder to handle than a system in which both OSes are installed in the same mode (BIOS or EFI).

  • Ok, I feel dumb! Just few minutes ago I deleted everything and install Windows again. Now a have two partitions, system secure (100 mb) and C (rest of hard disc)... same thing happen. Nothing is recongnized! Please Rod Smith, explain, what should I do?
