Recently threw out older version of Ubuntu because of failure to connect to router. Then decided to try 12.10. It connects easily. Unfortunately I am not given the option to install alongside WinXP. Since the older version was so installed, I do not understand.

If I click the 'Install' icon on the desktop I get a message 'Installer has detected a mounted partition - .... unmount or not?' I do not understand the significance of this.

Can anyone please help?

Terminal info is:

ubuntu@ubuntu:~$ ubuntu@ubuntu:~$ sudo fdisk -l

The mounted partition problem occurs usually when you have some memory card or some other memory devices inserted.
To install Ubuntu alongside with windows Xp do following:
First you should create a separate partition with the help of disk management tool in windows in which you can install Ubuntu.
Then after booting Ubuntu from USB/DVD, you should format the free space ext4 format.
At last install Ubuntu to this ext4 partition.

Use Wubi Installer, to easily install ubuntu alongside with windows.
