Question DualBoot Stock 4.3 and MIUI

Hello, I have been looking throughout google this afternoon and I've only found old tutorials and I will not trust anything happened to her phone.

He came to ask yourself if it is possible to make a dual boot with rom 4.3 ML2 vodafone Spain and the latest MIUI.

If you are asked and forgive me, I have not found.

Regards and thanks in advance
