I have an iMac 4,1 running OS X 10.5.8 that I want to install Lubuntu on. I have a USB drive and a DVD, both with the ISO burned to them, but I can't boot from either. They don't show up in Startup Manager at all. Both show up in the rEFInd menu, but when I try to boot either of them it tells me to make sure I have the latest firmware installed. How can I get one of them to boot? Alternatively, is there a way to burn the ISO directly to a partition on my hard drive and boot that way?

Which version of Lubuntu were you trying to install. Was is the name of the ISO file? Are you sure you are using a 32 bit version of Lubuntu?– David AndersonNov 21, 2019 at 1:10

@DavidAnderson It's 32 bit. The file name is lubuntu-16.04.5-desktop-i386.iso.– sheratekNov 21, 2019 at 1:35

Your idea of not using a flash drive or DVD might work by using VirtualBox to install Lubuntu directly to your hard drive. Usually, the procedure is fairly complicated. So, you really would have to want install Lubuntu.– David AndersonNov 22, 2019 at 7:22

Are you still trying to install Lubuntu?– David AndersonNov 25, 2019 at 22:45

Apologies for not following up sooner. I believe it may be the DVD drive. I don't have another disc to test it with, but it plays regular DVDs (although it's a little finicky sometimes). When I get a chance I'll clean it out and try again, otherwise I may look into installing it to my hard drive.– sheratekNov 27, 2019 at 13:38

I happen to have a 17" iMac 4,1. I burned the lubuntu-16.04.5-desktop-i386.iso
image to a RW DVD using a 2011 iMac. I booted from the DVD using the 2011 iMac and ran the software on the DVD to verify the DVD was burned correctly.
To boot from the DVD, you need start the Mac and immediately hold down the option key until the Startup Manager icons appear. Select the DVD icon labelled
Windows
.
Booting from the DVD using the iMac 4,1 was problematic. Basically, at some point the boot would fail. At least once the boot succeeded. After some research I learned I needed to hit the F6, then include the nomodeset
option before selecting Try Lubuntu without installing
. Once booted to Lubuntu, I could select the install icon on the desktop to start the installation process.
My iMac 4,1 has the latest firmware updates which are listed below.
Boot ROM Version: IM41.0055.B08
SMC Version (system): 1.1f5
The firmware information can be found under "Hardware Overview" in the System Information application display. Firmware updates for legacy Intel Macs can be downloaded from the Apple website About EFI and SMC firmware updates for Intel-based Mac computers.
Additionally, my iMac 4,1 has 2 GB of RAM installed and has a 1.83 GHz Core Duo (32 bit) processor.

Thanks for taking the time to do that! I tested the DVD on a MacBook and it worked, however, it won't even show up as an option on the iMac. I do have the latest firmware. Do you have rEFInd installed, and do you think it could possibly interfere somehow?– sheratekNov 22, 2019 at 4:06

I do not have rEFInd installed. I do not think rEFInd would interfere. I would assume the DVD drive does not work. Have you tried testing by booting from a 32 bit Windows (XP SP2, Vista or 7) DVD or a OS X (Leopard or Snow Leopard) DVD? Nov 22, 2019 at 6:21
