If you won't follow those steps installation problems can be minimized by running Disk Utility to Verify and Repair your Disk beforehand. Please backup your data first.

If you are having problems, three words: "Don't Panic".

Reboot normally and try the installation again -- it should work.
You're installer runs fine but progress has halted. Don't interrupt the process immediately -- installation can take a while and in many cases any slight flaws will be automatically repaired by the installer, so give it an hour before moving to the next step.

If the system does not restart in your previous OS X version then you must reinstall the OS.
Should any of these steps fail, please look to Apple Support. If you encounter other problems with your Mavericks installation then please let us know in comments below.
