I want to install Ubuntu alongside my Windows 7 operation system.
During installation I have three options:
- Install alongside the existing OS.
- Remove everything and install Ubuntu.
- Manual partitioning (advanced).
The above list is not precise (I do not remember what exactly was written there and I just write options as I have understood them).
I know that option 2 is not mine. So, I need to choose either 1 or 3. I do not know which one I need to choose. I want to have a possibility to manually specify space assigned to Windows and Ubuntu (for example 40% for Windows and 60% for Ubuntu).
I chose the 1st option and I saw a window with the following information.
Allocate drive space by dragging the drive bellow. File (48.1 GB) Ubuntu /dev/sda2 (ntfs) /dev/sda3 (ext4) 286.6 GB 241.7 GB 2 small partitions are hidden, use the advanced partitioning tool for more control. [use entire partition] [use entire disk] [Quit] [Back] [Install Now]
My problem is that I do not understand what I see. In particular I can press [use entire partition] or [use entire disk] and I do not know what is the difference. Moreover, as far as I understand, I can even press [Install Now] without pressing one of the two above mentioned buttons. So, I have 3 options. What is the difference between them?
The most important thing for me is not to delete the old operation system with all the data stored there.
