Or will it revert all the way back to Snow Leopard, requiring the discs? Yes, it should work just fine. Lion through El Capitan has the Recovery built-in, and it will reinstall OS X using whatever current version you are on.

If not, you might need to download the firmware to use the Internet Recovery version, but this installs whatever was originally on the computer, so you'd have to update your OS again from the Mac App Store. Everything works fine up until the last step after entering my ID and Password Try again later.

Would not let me reinstall OS X. Would any think it is more than a bad internal drive 1?

Whenever I turn on my iMac, it would load up to the apple logo and shut down after a few seconds. This happened ever time i tried to turn it back on again. I had a bit of hope but nothing ever changed so I decided to erase my disk and was immediately promoted me to restart my computer. When I did, it brought me a a symbol of a folder with a question mark which flashed forever.

I held the power button to turn it off and hit it to turn it on again while pressing command and R keys at the same time, it brings me a sign of a spinning globe that loads forever. When I restart it and immediately insert its installation DVD while pressing key C, it brings me the apple logo and stays like that for ages.

This is freaking me out. I have read and tried so may solutions online but nothing has changed. Please help me with another way. If I am currently running a public beta of El Capitan, will this method still work and install the official release of El Capitan?
