This is true. If you absolutely must use resource-intensive Windows apps, then Windows on bare metal is needed. This means either Windows as a host with Ubuntu in a VM, or dual boot.
ok.. so any good taturial for dual boting?

Not physical damage, no. But it is possible to corrupt both OSes so thoroughly that you will have no choice but to reinstall both of them. And if you are not careful, it is possible to mess your partitioning scheme up so that it is difficult even to reinstall. It is also possible to unintentionally erase all data on your HDD. In my case, my data is far more important than any OS (which I find no difficulty in re-installing).
good thing my data is not on the same drive as my Operating system but still, i will make sure to make backup before starting the process
