DMA-guide

This is a guide to dual boot with Singapore MOE DMA, without removing any files and the normal DMA.For educational purposes only. Introduction Instead of a normal computer booting only one OS, we can partition the disk and boot multiple OSes, including a fresh copy of any OS you want and normal MOE DMA. This improved method still allows you to login to your MIMS account and have a computer of your own that you can do whatever you want on. I am not liable for any damages caused. Exercise your own discretion.
