I recently installed Ubuntu 11.10 32 bit on my laptop. It is a Dual boot with windows 7. My laptop is a 64 bit system i had downloaded both .iso files and installed the wrong one. I would like to convert to the 64 bit OS But i didn't realize that i had installed the 32 bit version until after i finished setting up everything and configuring all my settings. I am wondering if i could either upgrade the 32 bit version to the 64 bit version and save settings or un-install the 32 bit version and install the 64 bit version and transfer all the settings and programs. If there is a way is it worth the work?
