That error indicates one of two things: 1)the installation failed due to the installer or 2)the installation failed due to a corrupt. I encountered this and it is quite a common diagnostic error when installing.

You may get a Data error in 'casper\filesystem.squashfs'.

It often can be a challenge and necessary trial-and-error process to see which version is most compatible with your hardware. If you consider an alternative download version, take care to consider the pros and cons of a netbook version (more compact but limited compared to the full desktop version), and an older (outdated by usually more stable) and newer (more up-to-date, but can be decidedly less stable) OS version. Download the appropriate version of ubuntu. If you have a netbook without a CD/DVD-rom drive, this is your only option for installing or re-installing any operating system. This is a useful procedure to know how to do (to avoid CD/DVDs).
