Any help to pointing me in the right direction would be greatly appriciated, and please let me know if I can post any details or info on my boot environment or configs to aid in moving this forward.

I'm currently setup with 4 partitions, (Retroarch System Volume), (Retroarch Storage Volume), (Puppy Volume), and I was able to do enough research to make Retroarch play nice with Grub2 after much config editing, however, I have not been able to get Puppy to recocognize the boot environment of the working Grub2 config, let alone its own auto-magically set up and installed grub4dos environment. I assume the issue is with grub(4dos), however I've not been able to pinpoint its grudge. I have tried the frugal install option to no avail, as upon boot I'm dumped to the grub4dos CLI. I just happened to notice that the old traditional install option is no longer available (to me) on the latest version, 9.5. Universal USB Installer aka UUI is a Live Linux Bootable USB Creator that allows you to choose from a selection of Linux Distributions to put on your USB Flash Drive.

I typically have used Puppy on most of my legacy hardware to great success, and am now looking to do the same on my 'new' old computers. Just a question about the current status of Puppy installation methods, as I'm coming back around to this distribution after several years away.
