What a creature is it?

I found it look here -

But I also want to know how. I already discussed this on a topic with user Mouratti, who tried to install the lite version on a tablet.

I have a 8 inch Android tablet with a x86 processor 2GBram and 32GB (possible emmc, not sure), never use it, so would like to install a lightweight OS, but don't know how to bypass the bootloader.
