    Hi guys.

    I have an iMac 20" PowerPC G5 2.1GHz. I have a tiger disk but when I insert it, it starts loading and then I get a grey circle with a line through it (like a road sign.) I don't know what else to do? I have tried USB but I only have Snow Leopard on my USB,

    Thank you guys for all your replies!

    Mac OS X 10.6 Snow Leopard will not install on your Mac, as 10.6 is only for Intel Macs and you have a PowerPC Mac, which uses a different architecture than Intel Macs.
    Also PPC Macs will not boot from USB devices, unless one clones Mac OS X onto them.

    The Tiger CD you have, is it the CD that came with the Mac or is it a Retail CD or a grey Restore CD from another Mac?
