HI I recently got a 1.25 iMac G4,,
A friend gave me a copy of leopard on a single layer dvd I could not get it to boot into it so I installed 10.4 Tiger.
Then I tryed a iso of leopard on the desktop it will reboot then never go any further with the install. Also evertime the computer starts it shows the grey screen like there is no hard drive then it boots.

1. Leopard does not come on a Single Layer DVD, thus your copy is missing some things.
2. We don't provide information on how to circumvent the law, especially when it is pirating.
3. It could have been a model specific DVD, which will not with any other Mac, than the one, it came with.

Yea you've probably just got some dud Leopard installations, you need to locate a retail one on a dual layer DVD.

Then if you have a legit .iso of Leopard, which is a bit unlikely, then why not use that? Burnt to a proper Dual Layer DVD of course.

By whom?
If it can read video DVDs, then it can read dual layer DVDs, as commercial video DVDs are dual layer DVDs (in most cases), but the optical disk drive (ODD) might have problems with some DVD-R or DVD+R media.

Anyway, your model might not be able to WRITE DL-DVDs, only SL-DVDs.

You have one copy on DVD by your friend, and one copy of an .iso file on your Desktop. Do you mean those with "2 different copies"? Because the latter is not bootable.
