Creating a USB Flash Drive Installer from a Snowfall Leopard ISO File

Below are three methods. The showtime method, which involves the Disk Utility application, failed to piece of work when tested using macOS Catalina 10.15.7 on an iMac (21.v-inch, Tardily 2013) two.9 GHz Quad-Core Intel Cadre i5. User John Marker Harrell's reply confirms this is besides truthful when using Large Sur on an unspecified Mac. And then the OP should probably attempt the 2d method involving the use of the dd command or the third method involving Balena Etcher.

Using the Deejay Utility Applicaton

This was tested using an iMac (21.5-inch, Mid 2011) 2.five GHz Intel Core i5 with MacOS High Sierra x.13.vi installed. The flash drive needs to exist at least viii GB in size. The Snowfall Leopard ISO file was the aforementioned as discussed in this answer, which should be the same ISO yous have linked to in your question.

Use the Finder application to mount the Snow Leopard ISO file.
Use the Disk Utility awarding to erase the wink drive, as shown below. I chose the default name Untitled. Finally, click on the Erase button.
Highlight the name Untitled, and so click on the Restore push on the pinnacle of the Disk Utility application window. In the popup window, select restore from Mac Os X Install DVD, as shown below. Finally, click on the Restore button in the popup window.

Using the Control Line Interface (CLI)

Annotation: This flashdrive will be using the Apple tree Sectionalization Map scheme. This differs from the wink drive created using the Deejay Utility, which used the Master Boot Record scheme. In other words, there is more than than ane way to create a USB flash drive installer from a Snow Leopard ISO file.

The steps below are for OS Ten and macOS.

Use the control given below to determine the identifier for the flash drive.

              diskutil list

Enter the commands given beneath to create the USB wink drive installer. Here, an assumption is made that the ISO file proper noun is snow leopard install.iso and the file resides in your Downloads folder. Likewise, an supposition is made that the identifier is disk2. If necessary, make the appropriate substitutions.
```
              DISK=disk2 diskutil unmountdisk $Deejay sudo dd if="$HOME/Downloads/snowfall leopard install.iso" of=/dev/r$DISK bs=1m                          
```

The steps below are for Linux.

Use the command given below to make up one's mind the name for the flash drive.

              lsblk

Enter the command given below to decide if whatever volumes on the wink drive are mounted. If there are mounted volumes, and so use the sudo unmount command to unmount them earlier proceeding. Here, an assumption is made that the name for the flash drive is sdb. If necessary, brand the appropriate substitutions in the rest of the steps.
```
              mount | grep /dev/sdb                          
```
Enter the command given below to create the USB wink bulldoze installer. Here, an assumption is made that the ISO file name is snow leopard install.iso and the file resides in your Downloads folder. If necessary, make the appropriate substitutions.
```
              sudo dd if="$Home/Downloads/snow leopard install.iso" of=/dev/sdb bs=1M                          
```

Using Windows 10

Note: Any version of Windows compatible with Balena Etcher should make an appropriate substitution for Windows x. User John Marking Harrell has also posted an answer verifying macOS Big Sur can be substituted.

Download Balena Etcher to Windows. This answer was testing using the portable version, which can be executed without having to be installed. The file downloaded was balenaEtcher-Portable-1.7.3.exe.
Use Etcher to wink the image stored in the ISO file to the USB wink drive. When testing the following pop-up appeared.

The image does contain an Apple division table, which is non recognized by Etcher. Since this bank check for a division table is not required, the message tin exist ignored. Select the Go along push button.
