There are several reasons to use UEFI instead of BIOS. I won't go into details regarding that. But there are some cases when you already have a fully functional Windows installation running on BIOS and you don't want to start all over again. Sadly, there
are no tools that performs this job. And I found there is not too much documentation regarding how this can be performed either, or even how this should work. Since after some digging and trial-and-error I was able to perform the operation, I will post the
instructions for anyone who needs it.
If you have any doubt, feel free to contact me. I will answer whatever (and whenever) I can.
Convert a Windows 7/8 BIOS (MBR) installation to UEFI (GPT) without moving, copying or loosing data.
Steps were performed on Windows 8. Some steps in Windows 7 may have different menus, but the options and results are the same.
