Ubuntu: Windows 7 detected, but no option to install alongside windows [duplicate]


This question already has an answer here:


  1. I want to install ubuntu alongside windows 7.
  2. I have 3 partitions on my internal hard-disk (C,D,E) and one external hard disk drive.
  3. I have removed external hard disk drive (from USB port) as i do not want to mess-up with my data on the this drive.
  4. I formated (as NTFS) my drive D in windows 7 to install ubuntu on this drive.
  5. Created a bootable USB with ubuntu 14.04.1


  1. Installation is showing Windows 7 detected but no option to install alongside windows.



output of sudo parted -l



*I formated my drive D in windows 7 to install ubuntu on this drive.

To clarify, is that partition currently unallocated space? Usually you need to shrink your windows partition before installing to provide enough free space for the new install. You might need to defragment your hard drive before doing so because linux will need a contiguous block of memory. If all of your files are scattered over the partition it might be impossible to shrink the windows partition enough for the install.

Edit: If you have already moved all data from that partition, then delete the partition to create unallocated space. This will be where ubuntu is installed. Ubuntu can't automatically guess that your NTFS partition is where you want it to install, all Ubuntu can use is the unallocated space on the drive.


At the moment, the simplest thing that can be done is delete the D: partition (not format it). Either using GParted or the Windows Disk Management tool. This will create unused space, which the installer can go ahead and use.
