Mac os x 10.5 leopard install dvd dmg. When I check my startup disks from preferences I can see the usb drive so I select it and click restart. I've done a bit of searching, and found these two articles:.The first article was written with Leopard in mind and does advocate the use of SuperDuper, much as you've done.With that said, one of the comments notes that you need to partition your USB thumbstick with a GUID partition table, and, while not stated, I would certainly use the HFS+ filesystem for your partition. Also I don't have firewire cable.So I created a.dmg file from the install disc and then copy that on a usb drive using SuperDuper. When it restarts I just get a grey screen and nothing happens.Also as soon as I open the computer (and desktop appears), the flash drive opens and I can click on 'Install OSX', same window that pops from the DVD. It asks admin password then restart and again the same grey screen.You think the problem is with making the bootable drive or with the.dmg file?I had to convert the installation disk from.iso to.dmg using 'convert' from disk util and then renamed the destination file to.dmg convert.
