In my laptop I have first installed Windows 7. Then, installed Ubuntu 11.10. Now my laptop contains two Operating Systems. I don't have internet connectivity in home. But I have Ubuntu 14.04 ISO with me,
i need to upgrade Ubuntu 11.10 with Ubuntu 14.04 without uninstalling Windows 7 and Ubuntu 11.10
. How to achieve this...
please help..am new one to Ubuntu.
As far as I know it is possible only to upgrade from one version to the next or from LTS to LTS. In your case that would be from 11.10 to 12.04 and then from 12.04 to 14.04. If you have only 14.04 available you can write it to a bootable USB and boot from it. At some point during installing, before you can do any "damage" to your existing configuration you will be asked how do you want to install (e.g. alongside Ubuntu 11.10 and Win or erase Ubuntu 11.10, etc). This is the place to check: if you find the option to Upgrade 11.10 to 14.04 you're in luck. If not, you have to backup your data and do a clean install.
