| G4 1.42GHz Mac Mini wont boot off DVD or USB | |
| Posted by: SpaceFlightOrange on 2023-10-30 13:47:15 Hi. Just picked up a Nice Mac Mini, 1.42Ghz, 1gb, 80gb. all seems to work ok, but i cant get it to boot off DVD or USB. I have burned a Tiger ISO to a DVD-RW (the only disk i had!) and when the machine has booted off the HDD it will read the disk ok, and if I select Startup Disk from prefs, i can see the DVD. but when i either select the DVD there, or hold down "C" on startup, it just boots off the hdd. If i hold down ALT on startup the DVD doesnt present itself. If i double click the "Install Mac OSX" it runs and then restarts but just boots off the HDD. I also have a bootable USB stick with the Tiger install DVD contents on, that i made and have sucessfully booted from on my G4 DA PowerMac, but the mini will detect it's presence (as can be seen in Disk Utility) but it wont mount it. I havent been able to test boot the DVD on the G4 because i only have a CD drive in it. an standard fat32 formatted stick mounts just fine. Im a bit confused by this. any advice would be great. thanks | |
| Posted by: SpaceFlightOrange on 2023-10-31 01:23:02 Just to follow up to this, I have managed to get it to boot from a MorphOS CD, so it is capable of booting off a disk. Is there anything specific i should do when burning an iso for boot? | |

Posted by: SpaceFlightOrange on 2023-10-31 08:06:50Try burning another image of 10.4 (10.3 is also supported) - sounds like it just isn't quite rightyeah. I did wonder. I burned the iSO using imgburn on PC as my M1pro refused to burn it to my external burner for some reason, but it was on a DVD-RW, literally the only blank DVD I had. I've ordered some DVD-R. hopefully they may work a bit better. I'm quite puzzled about the USB stick though. this stick took some effort to set up and get working with the PowerMac DA and I successfully booted that and installed Tiger with the stick. yet the Mini won't even mount it. | |

I'm not familiar with imgburn to say if it is an appropriate program to use or not. | |
| Posted by: LaPorta on 2023-10-31 08:41:41 As far as the USB drive, sometimes there are versions of Tiger that came out prior to a particular machine being released that will not work with a latter one. What version of 10.4 is installed on there? | |

Does it show up in Disk Utility? Have you tried another USB port in case one is broken? EDIT: I just saw that part buried in a latter response. Have you tried to manually mount it with Disk Utility, and what did it say? Also, what format is the USB drive in? | |

But instead of using the OS 9.2.2 image, you’d use a Tiger ISO. https://macintoshgarden.org/apps/mac-osx-mac-os-10-ppc (#32) I begin OS X installs on G4 Minis here with 10.4.6. [The original 1.42 GHz G4 Mac mini installer disc installs 10.4.] | |
| Posted by: SpaceFlightOrange on 2023-11-03 07:12:15 Hi. An update. It was the disk. seems my mini doesn't like booting of a -rw. it was the only disk I had so was stuck for a few days until my new DVD-R's arrived but then I was stuck for 18hrs because they were delivered to my neighbour and they didn't answer the door when I tried to retrieve the parcel numerous times! Prior, I tried erasing and re-burning the -rw, this time using my intel Mac mini running Snow Leopard, but no joy. It's a PPC only version of Tiger I have so couldn't test on any of my intel Macs. I also checked the USB stick I originally used to install Tiger onto my PowerMac DA, and it turned out that was corrupt. so I had another go with an SD card this time and while it works fine with the PowerMac, the Mini refused to boot from it. But, using a DVD-R slow-burnt on the Intel Mini, the g4 Mini booted right away, I now have a fresh install on the machine. Thanks for all your advice | |
