New hard drive - how to format when boot option doesn't work?
I purchased a replacement HD for this computer and installed it today. I am unable to start with the boot option (option key down) or from the original installation disks for the iMac.
Holding the Option key down on startup does not display the boot option menu. A blue screen is all I get with two small rectangle buttons - one with a refresh and the other with a forward arrow. Clicking either produces no results.
Attempting to start from Installation Disk 1 or Disk 2 does not work as neither appears to have a proper system folder.
All of my Macs are much newer than this one and the CD's will not load in those.
I appreciate any ideas or suggestions on how to create a startup disk/volume that I can use to format the new drive and then install the OS.
