I installed a new 2tb hard drive hard drive because the original one had failed on my 2010 iMac. I'm having trouble installing the operating system onto it. I get the blinking folder with the question mark. I'm using a USB keyboard holding C at start up with the original OS install disk in the drive but it just ejects itself everytime. I've also tried holding down option command and R and still nothing with and without the install disk. I've tried other keyboard combinations I've found on the board but nothing has worked. Any suggestions?
