I have Windows 7, and I'm trying to dual boot Windows 7 and Ubuntu. However, when I try to install Ubuntu with a USB, it doesn't give me the option to dual boot. I can only "Replace Windows 7 with Ubuntu", or "Something Else".

I've installed Ubuntu on this computer before, and this option was present. What I'm asking for is a way to get that option, or how to use the "Something else" option.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

How many partitions do you have. If you happen to have 4 primary partitions, then Ubuntu will say to replace your existing Windows since there are no more primary partition slots left (The maximum is 4 primary partitions).

Check to see if this is the case and decide which partition you wish to remove or change to a logical partition.

The explanation (With images) can be found in Is it possible to have Windows 8 and Ubuntu on the same hard drive?

The answer should give you an idea of how to remove one of the primary ones and create a logical one which can be extended to several partitions.

@Jason That means you have 4 primary partitions. Going to put the explanation here. – Luis Alvarado May 22 '13 at 1:44
