Mavericks installation stuck at 18 minutes mark I am trying to reinstall Mavericks an 27 inch, Mid-2011 iMac

The hardisk has been reformatted, and I have created one partition Mac-HDD in it.

I have created a Mavericks usb installer using this command:

sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia \
--volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction


Can you suggest anything I can try?
You can show the install log by pressing cmd-L. Make sure you're showing all messages and look at the bottom of the log. This may give you a hint as to what's happened (or happening).
