I am trying to Install the latest Ubuntu 13.04 on my netbook but the installation is not able to detect any operating system installed on the machine. And asking me to either wipe out the whole disk or repartition it. I have already installed Windows 7 Strater, Android x-86 and Meego installed on my system.
During install it says " This Computer currently has no detected operating system"
Here is the output of sudo sfdisk -luS && sudo fdisk -l:
Disk /dev/sda: 30401 cylinders, 255 heads, 63 sectors/track

DOS and Linux will interpret the contents differently.

For this listing I'll assume that geometry.

I have tried this workaround but it is not working in my case. Any prompt help would be appreciated. I request moderators to not to immediately close this question even if they think it has been previously solved as those solutions didn't worked for me.
Thanks in Advance.
Edit: Now I have deleted the other two Operating systems namely Meego and Android-x86 but still no avail. The partition table now looks like this.
