I am trying to install Ubuntu on dual boot with Windows 7. I already created a partition, but for some reason Ubuntu does not give me the option to install along side Windows 7. So I thought let's install Ubuntu in that partition manually. Only thing is that Ubuntu is not detecting my partitions in the hard drive. What do I do? It says that I can create a new partition table, and all other partitions will be deleted. Will I lose my stuff like that?
