I want to install Ubuntu 13.10 alongside my Windows 7 and Windows 8.1 operating systems.

When I boot up from the live CD, it doesn't give me an option to install Ubuntu alongside Windows.

I tried clicking on something else too -- it just showed my whole disk as one unallocated partition.

I don't think I have 4 primary partitions either. I once converted them to logical partitions too!

Can someone help me to install Ubuntu?

I have a 1TB hard disk and I have only used around 200 GB for both of the operating systems! I have lots of space left. What do I do now?

  • add the output to your question: run sudo fdisk -l and sudo parted -l I'm assuming you have the GPT-disk

  • @JohnnyD - you can get most of the info from the image... harikrishnan, there are likely two main reasons for this - you already have a dual boot of Windows 7 & 8 - and there is no space on the disk for Ubuntu to be installed on.

    @Wilf you are right but there's always something like MultiOS which is more than 2 OS help.ubuntu.com/community/MultiOSBoot

Your problem is almost certainly caused by leftover GPT data on an MBR disk. You can correct this problem by running FixParts (part of the Ubuntu gdisk package) on the disk. Once you've done that, you should be able to resize partitions to make it all work.

Also, be sure to disable the Windows 8 Fast Startup feature. This feature is incompatible with a dual- (much less a triple-)boot configuration.
