Is it okay to copy paste some part of my Bachelor's thesis literature review for my own Master's thesis?
Obviously you should check the regulations at the institution that you are attending to see exactly what they say about this matter.

With that said...

Submission of a thesis often includes signing a declaration that the material contained within the thesis has not previously been submitted for consideration for another degree (or words to that effect).

By doing what you suggest, copying and pasting a sizeable chunk of a previous thesis, you would be violating this declaration.
