I recently purchased a new 160GB hard drive for my MacBook Pro to replace the stock 80GB one inside the computer. With it, I also purchased an external USB 2.0 hard drive enclosure. My plan was to put the new 160GB HDD into the enclosure, install Mac OS X 10.4, transfer all my data over from my old 80GB drive, then open up my MBP and install the 160GB HDD. The 80GB drive would then be installed into the external enclosure. The problem I'm having is installing Mac OS X from my Tiger install DVD on to the new 160GB drive. I can't open up the install application and target the new drive. Is there something I'm missing? I know that on older Macs, only FireWire drives could boot a computer, but that newer Macs could boot from a USB 2.0 drive. So, what do I do to install Mac OS X to my new hard drive that is hooked up to my MBP via USB 2.0? Thank you for your help!
