What mean this error while booting?

boot

Solution 1:

This message can be safely ignored. For anyone coming from a Google search, the complete message is this:

i8042: Can't read CTR while initializing i8042

The message will appear when the Linux Kernel is unable to locate any PS/2 controller. Given that you are using a tablet with an Atom-based processor, it is unlikely that the system contains a PS/2 controller as everything — including the keyboard — is run through USB.

That said, you will probably want to look at using Ubuntu MATE, Xubuntu, Bodhi Linux, or another light-weight distribution. Stock Ubuntu requires 4GB of RAM, which your tablet lacks.
