1. How much space you should give to Ubuntu while dual booting ?
Ans: If you are dual booting Ubuntu only for this workshop, you can give around 100 GB space. Allocate 30 GB for Root ( / ), 8-10 GB for swap area, remaining for Home.
If you are planning to use Ubuntu furthur, dedicate full D ( E or F ) drive to it ( 300 GB in most of the cases ). Give 30 GB for Root, 10 GB for swap area, reamining for Home.
