Hi, last year, i bought a Mac Mini on ebay and it came with snow leopard already installed. Its been working great but today, i decided I want to swap the 80gb drive for the old 320gb drive from my laptop (the laptop got a shiny new SSD). Problem is, when i try to boot from the 10.6.2 install disc, it says that snow leopard cannot be installed on this Mac. Any way i can get it to install Snow Leopard on the new drive? Also, I tried running the installer on the old HDD from inside the old Snow leopard install and it also said that it could not install snow leopard. It then asked me to restart and kept attempting to install Snow leopard and failing. specs of Mac mini: -Model Identifier: Macmini1,1 -Intel Core Duo 1.83GHz -1Gb 667MHz DDR2 RAM -4 USB ports for the record, i think the guy i bought it from bought a new mac mini and just included the discs that came with the new one in the one he sold me. The instruction manual shows a mac mini with a mini display port. The only OSX disc i got from him was the snow leopard one. also, if it matters, this mac mini is the only mac computer that I own.
