Convert DMG to ISO and Create macOS Boot USB from Windows

Since ISO is a better format for Windows, you can also convert the DMG to the ISO format and then use the ISO disk image to create the bootable USB. Please note that you can't boot your Mac from bootable USB made from an ISO file, which means you'll have to convert it back to DMG prior to that. Still, it's an effective way to create bootable media for a Mac computer. Here's how it works:

Step 1: Once you have the macOS install DMG file on a Windows PC, click on Windows + R to open the run dialog box, and type in CMD, then hit Enter. When the Command Prompt opens up, use the following command to convert the file to ISO:
hdiutil convert /path/sourceimagefile.dmg -format UDTO -o /path/targetmage.iso

Step 2: Download and install UUByte ISO Editor on your PC, insert the USB drive and launch the application.

Step 3: Click Burn button on the main screen and point to the converted ISO file. The drive will be automatically detected and click on Burn icon to burn the ISO to the USB drive.

Once the ISO is burned to the file, you can insert it into a Mac and convert it back into the DMG format. Since you're converting the file twice, there's a chance that the file could get corrupted in the process. If that happens repeatedly, then try this next method.

All,
I just bought my first MAC G4 Dual 450 from a friend (who bought a new G5). He gave me .dmg files of the panther disks 1-3 and the X code as well. I have now coastered about 10 disks trying to figure out how to burn a bootable CD so I can reinstall Panther to 2 40G disks (internal) instead of the 1 20G disk I got with the machine. I also have a 160G external Firewire disk and a Plextor PX-716 DVD/CDR burner.
I can't seem to get this to work right. I am a Linux user and can burn bootable CD's from image files all day long, but this is just killing me and getting rather expensive.
I have made sure to mount the dmg file for each of the 4 disks, tried just burning a data cd, then burned to an image and burned the image to cd, tried a mac volume, nothing seems to work. Yes I have made sure to hold down the C key after rebooting and putting in the new blank HD's. Also tried to option key to see what bootable device is there and with the 2 new blank HD there is nothing. All I see if I hold down C is a blue screen with a little folder with the MAC picture and then a question mark flashing back and forth...I am using Roxio Toast Titanium 6.0.3 to try to burn the CD's
Can someone please, please help me so I can use my 2 new 40G HD's?
Thank you VERY much in advance
Rockstar/Michael
