How to replace Windows 7 with Ubuntu 12.04 in C drive without affecting other partitions

Question

In my PC (2 GB RAM, 160 GB HDD) I have Windows 7 in Partition C (20 GB). I have tried Ubuntu 12.04 from Live USB. I now want to replace Windows 7 with Ubuntu 12.04 in the same C Partition without affecting the other partitions and their contents. I have read the answer to a similar question but still do not feel confident. Like in that question, I too have proceeded till "Something Else", but then precisely what steps should I take? Is it possible to simply choose the C Partition and start installing Ubuntu there? In that case what other choices should I make?

Answer 1

After something else:

• Select Windows partition and click on "-"(which is beside the "+" icon).
• Now it shows it as an unknown partition. Click on "+" button. You'll get a window to manage that memory.
• Choose: "Primary partition", "Beginning of the memory space". Size as (8-9)GB. (1-2)GB is left now as free space.
• Select 1GB space and click on "+" icon and choose options like this: "Primary partition", "Beginning of the memory space", "swap area".
• Click install.
• Comment.

Answer 2

Just create a bootable USB of Ubuntu ISO file. (Make sure your important files are not in Windows 7 partition)

Restart your PC and boot up your USB. While installing, select "Replace Ubuntu with Windows 7"

That's it!
