Trying to wipe the hard drive on a G5 iMac, using an external DVD drive as the one in the iMac is broken.
I'm trying to boot up with the OS (or install) disk, from an external DVD drive as the one in the iMac is broken. When the computer boots up, my normal desktop appears, but also the Mac OSX (Tiger) install disk. When I double-click on the "Install Mac OSX" icon, a screen comes up that says: "Click the button below to restart & begin the install process". The iMac restarts, but just goes back to where it was, & I'm prompted to: "Click the button below to restart & begin the install process".
So far there is no way to "begin the install process", I just keep going around in circles with this. I'm doing this so I can sell the computer. I hope I've made it clear, and TIA for any advice.
iMac, iOS 4.2
