I'm trying to install Ubuntu along with my existing Windows 8 OS (the computer came with Windows 7 so I'm supposed to have the old BIOS).

The problem is that when I tried installing Ubuntu from a USB drive I didn't have the option to install it alongside Windows, I've been told that the problem is that I've got 4 partitions and more partitions just can't be added. Partitions

These are the partitions I have on my machine, I think I'll try resizing the Windows7_OS partition in order to free some space and delete one of the others partitions. The question is which one can be removed safely.

Other solutions for running Ubuntu will be appreciated as well :)


I'm using a U310 which is supposed to have 32GB SSD storage as well as 500GB HDD Storage

  • Looking at that setup, what is on your D: drive? that might be a great place to consider resizing or even deletion (did I mention backing up first?). I should also note that the drive you have in your U310 is a hybrid drive meaning that it uses the 32GB and the 500GB in tandem to move frequently accessed data to the SSD and switching those that haven't to the HDD. I don't think you get much control over how it does though...

  • @Mordoc The D: has some files that can be easily transferred, and a Drivers folder that contain what looks like the installation files of the drivers. Do you think I should delete it?

    I second @Mordoc. Backup and remove D:. Do not format and keep in unallocated so that Ubuntu installation process can find it and create its own sets of partitions / and swap. But you may have another problem. See: Can't see HDD during install of 12.04 on Lenovo U310

  • @user68186 Why don't you submit yours as the answer and I'll upvote it, that is a better answer.

1 Answer 1


There may be two issues here.

First, as you have found out you need to delete 1 of 4 primary partitions to create more (extended) partitions. I second @Mordoc's comment above. Backup and remove D:. Do not format, keep in unallocated so that Ubuntu installation process can find it and create its own sets of partitions / and swap.

If you want more space for Ubuntu, you can shrink C: and make the unallocated space a bit bigger.

Second, The 32GB SSD is used by Windows in such a way that is not compatible with Ubuntu installation. This has been discussed before in another question. See Can't see HDD during install 12.04 on Lenovo U310 for a solution to that problem.

See Is a 40GB SSD practical to use for ' / ' for some ways of using the SSD and HDD for Ubuntu.

Hope this helps
