I just downloaded both the 32-bit version of 12.04 LTS Precise Pangolin and burned it onto CD. When trying to install there is no option to install alongside win7. I tried the 11.10 CD and the option was there. I ended up having to install 11.10 and then upgrading to 12.04 online. Why was there no option to install alongside win7 with the 12.04 LTS CD?
Not sure. But you can boot into the LiveCD, then use gparted to shrink your windows 7 partition, and then reboot into windows 7 to make sure it's clean. Then you can reboot to the LiveCD and install Ubuntu. If windows 7 craps out on you from changing the partition size. You can fix the boot repair process with the free CD downloads from: http://neosmart.net/blog/2009/windows-7-system-repair-discs/ . You may want to download those and have them ready, if you don't have a windows cd.
