OS X Mavericks Official Installer
Official OS X Mavericks .app Installer from the Mac App Store.
Un-archive the zip archive and you will get the app Installer. A bootable ISO or bootable USB can be made from this installer. Instructions on how to do that are on the Internet/Youtube.

NOTE: If you get a damaged message when launching, no need to worry. Run this command in Terminal:
xattr -cr "wherever your installer is. drag and drop into terminal, and remove quotes." Please don't complain about this in the review section I literally put the solution in this description.
NOTE: While installing, if you get an error message such as Apple can't verify your computer, change the date setting to November 1st, 2013 in Terminal or System Preferences. It should work after that.
