I use Frugalpup Installer main program this way to do installs to USB drives. Actually any drives.
viewtopic.php?t=11171
I know it seems like a lot of steps.
But I wanted to make sure it was fully understood what to do and when.
When you setup the partitions on the drive.
The 2nd partition or any other partitions except the first one, you can make any format you want to.
exfat if you want.
The frugal install goes on any other partition(s) other than the 1st one, which is just for the boot loader files.
Note:
Make 2 partitions is best.
Putting all other frugal installs on the 2nd partition.
Makes it easy for the Frugalpup installer boot loader install to see all of them to make menu entries.
It only has option to look in only one partition you tell it the frugal installs are in.
Why do we even want to use exfat?
The exFAT format is the best for big portable storage devices on both Windows and macOS operating systems.
exFAT is also highly supported by both Windows and Mac computers, and users can flexibly use exFAT storage devices to transfer files between two systems.
Note:
For a Puppy save placed on exfat format.
You have to use a save file.
Cannot do a save folder.
Example:
This is a 512GiB USB drive I have 7 different Puppy versions on, each in their own frugal installs.
All the frugal installs are on the 3rd partition.
The 2nd partition I use to store data.
1st partition has the boot loader files, with boot loader menu to boot any of them.
Booting from it running BookwormPup64 10.0.6, right now.
