OS update error

[NCBeee]

I recently got a prompt to update the OSx so after clicking update it took me to the install screen . After selecting which drive to use it began installing without a problem for about 5 minutes shortly after the installer froze saying an error had occurred. Ive repeated this multiple time and the same thing happens . Time machine is not usable. Quitting the installer does no good . Any advice on fixing the install or possible returning to the old OS

Are you talking about the recent OS X 10.9.2 update?

First do a command-r boot to recovery then use Disk Utility to run a repair disk and make sure you have any disk errors going on.

Then reboot back to a normal login and try downloading the combo update directly from here then running it.
