I'm trying to install the latest 64-bit build of Ubuntu (13.04). Unfortunately, during install Ubuntu can't seem to partition my drive correctly.

My primary drive is a 128GB SSD. I want it dual booting with Windows 7.

With Windows 7, I resized my primary NTFS Windows partition to create 20GB of free space. When I select that free space for Ubuntu to install on, I receive the following warning:

Some of the partitions you created are too small. 
Please make the following partitions at least this large: /2.9 GB  
If you do not go back to the partitioner and increase the size of these partitions the installation may fail.

However, I do not know which partition it's asking me to resize.

Any suggestions on how to fix this?

Please boot into the Live CD/DVD/USB and add to your Q the result of sudo fdisk -l. – TomKat Oct 5 '13 at 9:50

Have you tried choosing manual install and manually reformatting free space?

Basically follow this guide :


  1. Make two partitions from free space, one primary ext4 mount at /, one primary linux swap.

  2. Choose /dev/sda to install GRUB on.

  3. Continue with install.
