Q: My Big failure to install maverick in Macbook Pro with retina

Can you elaborate your problem. Have you erased your disk? Can you start in recovery mode? What version were you upgrading from or were you clean-installing it? What is your state now?

When i was trying to clean installation it failed to complete.

At what step did it fail to complete?

How are you installing Mavericks, a usb disk, a dvd or recovery mode.

Did your machine come with Mavericks or Yosemite?

If it came with Mavericks, you will need to erase your drive using internet recovery and then reinstall the original OS.

If it came with Yosemite, you cannot install Mavericks.

What OS was installed when you bought the computer?

How did you get to install Mavericks please help me I have the same problem with my rmbp mid 2015

If yours is a 2015, you cannot install Mavericks. Macs cannot boot from OS versions older than what they came with. I believe yours came with Yosemite?
