Windows 7 Boot updater error.

[Mcpe2014]

Hi everyone I wanted to change my boot animation in windows 7 ultimate x64, using windows 7 boot updater and i got this error:The winload.exe path in the bcd is an EFI file wich is currently not supported. After more research, i found out that this is becuase i have a UEFI installation of windows 7. Is there any way to convert my windows 7 installation from UEFI to regular BIOS without loosing any of my personal files ? Thanks in advance

I assume you have a gpt disk which and would want to convert to MBR so the whole thing is a massive backward step all for a bit of animation
