    How to reinstall Windows 8 on UEFI from a Windows 8 Legacy


    So I fresh installed Windows 8 on Legacy boot, deleting all partitions even the factory restore partitions, everything. I realized late that the new trendy thing is to install on UEFI, however I'm having difficulty doing this. How exactly do I go about this?

    My laptop has a 256 gb SSD mSATA where Windows and apps are installed, and a media HDD sized at 750 gb. I deleted every partition I had when I installed Windows 8 and made new ones for a fresh install, however I think this is preventing me from doing a UEFI install correctly..
