Hi, I'm typically a Windows guy, but have recently become interested in Apple products. I have an older iMac (2006 vintage, I believe). It wouldn't boot anymore so I opened it up and removed the HDD, replacing it with a new one. After reassembling it, I started it up, inserted the O/S disk and expected to see the HDD as an option for the O/S installation destination. However, there is no drive listed in the box when it asks to select the destination.
Is the drive not being recognized for some reason or is there something I need to do to have it show up as an option?
