Just a short article this one. I just got a new motherboard that support UEFI after a long time with my old one. I didn’t want to reinstall Windows at this point and it did a great job of detecting all of the new devices and just booted no problems.
However I would like to take advantage of Windows’ ability to UEFI boot and use the Secure Boot feature on Windows 8. There is no supported way to migrate from BIOS booting to UEFI but it is possible to do it. This isn’t for the faint of heart and it’s always possible when messing around with things like this that it’ll leave you in an unsupported state or completely broken and require a rebuild.
It did work for me though. Check out this great article http://social.technet.microsoft.com/wiki/contents/articles/14286.converting-windows-bios-installation-to-uefi.aspx for the instructions.
