Making OSX 10.5 Install DVD for iBook G4

[System6+Vista]

Just aquired (via another 68kMLA member!) a beautiful iBook G4 running 10.4 and I would like to install 10.5 Leopard on it. Actually, previous owner had partitioned the disk with a half where 10.4 is installed and the other partition was already reserved for 10.5 but he was told that the iBook can't dual-boot? I don't see why not, even if I have to hold down option every time I start up to choose which "disk" to boot from.

Anyways I have found disk images online for 10.5 and they appear to be good - at least the folders are all there, it can mount on my 10.14 iMac, it got like almost an hour into installing on the iBook happily before it croaked and said there was an issue with one of the files on the DVD I burned. I wasn't exactly surprised because when I burned the image it said that it couldn't verify that it was good (I forget the particulars). I am trying to download the iso from a different source, hoping that may be the cause: https://archive.org/details/OsxLeopardInstall

Any ideas / known good iso sources? I tried to Verify in Disk Utility but couldn't.

Your iBook should be able to dual boot 10.4 and 10.5 -- exactly how you've done it by partitioning the disk (in either one) is the right way to go. You'd either have to use the startup control panel or hold option to switch partitions, exactly as you have been doing.

The failure you showed in the picture is either a read or write error. The installer tried to get that file off the disc and it either couldn't read it, or it couldn't write it back out to the hard drive.

You can:

• Reinstall the OS but without whatever component used that package (do a custom install and then uncheck additional speech voices)
• If that fails, e.g. with another package that has a read error, perhaps try an install of the bare minimum.
• Then, re-burn the installer to a new disc
• If the second burn fails, I would find a new rip, whether from mac{garden|repo} or I can go look to see if there's a 10.5 image on vtools, or another member might have a disc they can rip (on a windows computer with something like imgburn would probably be the best and most consistent way to do it but OSX rips and OSX burns should also work)

Given that you've already confirmed the image itself thinks it's damaged, it may be worth skipping to finding a new image entirely.

Thx muchly, Cory. Yes, since posting I did move onto another image (or at least from another source, I didn't even bother to check if the files are the exact same size). I'm thinking what's happening here, though, is an issue with my DVD+R media, I will have to try another type. The drive I'm using to burn the DVDs I bought new in 2020, Samsung brand, USB DVD writer. I've burned discs sucsessfully, but I'm realizing now those have only been CD-Rs and Single-Layer DVD-Rs. I got this giant spindle of DVD+Rs which perhaps aren't going to work for me.

I don't think I confirmed the image thinks its damaged, I led you into thinking that because when originally posting hadn't remembered freshly what the error message was - the error was that MacOS couldn't verify that it had burnt the disc correctly. Sounds like media isssue, yes?
