I have been using ubuntu 12.04 and the update cannot work out. So I'm trying to erase ubuntu 12.04 and install 14.04 directly to the same partition of 12.04. My computer is running wondows 7, with ubuntu 12.04 installed alongside. When I run the installation, it asks me the installation type. It detected that I have multiple systems installed, and gives me these choices:
- Install Ubuntu alongside them
- Erase disk and install Ubuntu
- Something else
I definitely don't want two versions of ubuntu, and I want to keep my windows 7, so I have to choose "something else". And here's where I am unsure about. It asks me to choose a device for boot loader installation. Apart from windows system related disk space, I have two partitions under /dev/sda:
- /dev/sda5 ext4 (Ubuntu 12.04.5)
- /dev/sda6 swap
My Ubuntu 12.04 is installed in the partition /sda5, but I don't know what /sda6 is used for. It has around 4GB space and 0MB is used.
If I double click the format little square button, this window will pop up:
It looks like I can also choose to change the size but I suspect that it wouldn't be safe to do here.
So how should I configure this?
I am changing the settings of my /sda5 in this way:
And /sda6 is automatically chosen as swap area. All other ntfs partitions are left as do not use the partition. Boot loader should be installed at the beginning of the drive in which your ubuntu is going to be installed. (In my case, it's /dev/sda/.) So my final settings are like this:
Click install now, and it Worked!!! Thanks everyone!
