It can be done in a few steps: Open the Bootloader - Connect the device to WiFi - Enable the Developer options menu by clicking on the build number 7 times.
Chameleon can be considered as the original bootloader, as Chimera is a fork ripoff of it and legacy Clover uses much of the same concepts from Chameleon.
I have a problem when i turn on my pc and get the Chimera boot option(i have mac and windows in different hard drives),if i boot onto windows 7 works fine.
