Too many Partitions on drive, can't dual boot ubuntu alongside win8 on Thinkpad

I have a Thinkpad S431 with Windows 8. It has a 128gb SSD, and My partitions are WINRE_DRV, Windows8_OS, Lenovo_Recovery, 7gb Hibernation Partition. I also have allocated 20gb for Ubuntu.

When I tried to install Ubuntu, it told me that I have too many OS's on the machine, and the new partition I created is labeled "unusable".

What can I do?

Edit: Volume type is MBR.

I have deleted an unnecessary windows 8 partition from Gparted in the Try Ubuntu option. From there I have also formatted the drive to be ext4 on /dev/sda4 Now the problem is that Ubuntu will not install as "root file system is not detected"

I used ext2 as the filesystem for Ubuntu, and mount as '/'. This solved my problems!

You must make extended partitions. A MS-DOS partition table allows a maximum of 4 primary partitions.

Don't try to shrink or split a primary partition in two that is located before the extended partitions because you may alter partition table.

I also have allocated 20gb for Ubuntu.

Instead of allocating Ubuntu partitions from Windows, you should delete/shrink partitions to leave empty space in Windows. Then let Ubuntu partition manager create partitions on that empty space.
