that s how we reboot our macs.The SSD is here (it was the Macworld SSD temp sensor that I was waiting for, you would not believe the price of this lead delivered to the UK, with P&P, customs tax, UK post office charges!!!) - It's just that I daren't put it in!!
So are you saying that you think I can install the new SSD, boot with CMD + R and the iMac will start doing its thing?
watch that video tubemans posted *7, that should be detailed how to reinstall your drive.
