Start up issues

Tried to turn on my iMac last night, as normal the apple logo appeared with the loading bar...... and that was it.

Loading bar took much much longer than normal, got to 100% then just sat.

Have tried getting into the recovery menu (cmd + R) but every time the loading bar comes up and does the same thing again.

Am planning on taking a wired keyboard home tonight to try that but feel like i'm clutching at straws?

iMac is a 2007 21" running what ever the latest version of OSX that it can (basically i do all updates when they come on the app store)

Any suggestions

Failed internal hard drive?
After all, it's going on 11 years old.

You need a fully-bootable external drive.
Connect it and try to boot that way.
If an external drive boots the Mac when an internal drive won't, that's pretty indicative of the situation...
