How can I covert a MBR to GPT partition map?

Mi imac don't restart after the 10.8.4 update, and the solution is reinstall OSX restoring the HD.

i'm using a external hard drive to clone the content of my HD, but its a MBR partition map, and it says that the process can only be done with a GPT partition map.


anyone who knows how to convert from a MBR to a GPT with a mac?

after converting the external HD, may i change again the partition map to his native MBR partition?


Many thanks.

iMac, OS X Mountain Lion (10.8.4)
