I am currently running 10.4- Tiger. I never updated because my optical drive went out and I never got it fixed. I called Apple and they said that I could upgrade to Snow Leopard, but not Lion. So I have purchased Snow Leopard, but don't know how to load it. Here's what I've tried:
1) Remote Install- from an imac and mac mini. It won't recognize the connection.
2) I made an .iso of my Snow Leopard disc in disc utility. I put it on a flash drive and tried to boot. No going. I also tried to mount the .cdr directly from my desktop. It goes through the beginning prompts and then says that I need to reboot to begin installation. I suppose when it reboots, it loses the mount and doesn't begin the installation.
Long story short, any suggestions?
