Well - how you get it there is immaterial - but booting into it is one easy way. Wherever you have the logo, just
sudo cp logoname.png /boot/vmlinuz-linux.png
that assumes you did boot into the destination distro of course!
And it assumes you’re in an EndeavourOS install too!
I’m not great with terminal . I have to think too much. 
So I usually take the route of least resistance but it does take longer for sure. I’m terminal coding challenged! I try hard!
Okay so that’s pretty easy! Now i label the partitions and what does that do for me?
I do understand the command …i just don’t do enough of it. So i have to think too hard! 
It just makes it easier to figure what you’re booting from. You’ll notice it says something like Boot /boot/vmlinuz-linux from filesystem-name when you select one of the non-Windows entries. Examples can be seen on the screenshots in the wiki on rEFInd…
So do you have xfce on your ssd to do your work from as shown in the case study? I also notice xfce in the list of the 9 partitions. Just wondering?
On that machine, the ‘daily driver’ is the EndeavourOS logo, pointing to a /root /home split on the SSD - and yes, it is XFCE.
My MAIN daily driver is on another machine, and the current list is like this:
Arch xfce
Arcolinux xfce
EndeavourOS xfce
MX 19 xfce
Xubuntu
Sensing a theme here? I also have a few other things for testing out (Cinnamon, lxqt (was deepin) Plasma, Gnome, Mate - but the actual use systems seem to end up xfce now 
I see an Xfce theme here. Why is that? I also would like to run Anarchy but i can’t remember if rEFInd would boot it with the others? I know i have issues with it on with grub. That’s one of the reasons i want to switch.
Edit: So with the 8 distros on that drive you don’t have a home partition? But you do on the SSD. So you just access the 4TB drive for files.
I’m thinking about putting Xfce on the drive with Windows 10. Then taking the two NVMe drives and put 4 partitions on each and i could have the swap on the ssd. I don’t normally use hibernate and i have 32 GB memory so do i really even need swap? Maybe i should add a swap file instead of a partition for swap on the SSD. 
I read an interesting discussion on the merits of having a swap available. It might seem not to be needed in theses days of large memories, but its existence can have an effect on how the system runs anyway. Basically it affects what can be used for cache and other factors - which can impact performance in a large way. Have a swap! I have a chunk on the nvme drive, and point all the different distros at it - as I don’t have to run more than one at a time, so there’s no conflict as I don’t hibernate either… I also tend to use a partition, as it’s a set and forget option!
As for partitioning, you can end up with a lot of them if you don’t plan ahead a little bit! On the other hand, it can be tricky to resize them later - although possible with ext4.
The way I look at it is - no matter what you choose - you’ll th8ink of something better later So - just make it happen - and make good backups!
I have never been much of a backup person. 
I still haven’t figured out what that is trying to set up - so I couldn’t guarantee anything. I might try it again later, as I’m thinking about redoing the entire other system differently - so I wouldn’t be losing anything in case of ‘errors’. Right now, though, that system is seeming to have temperature issues (it goes for days just fine, then I suddenly notice that it’s at 102C! Doesn’t seem to bother it, but it bothers me. Pulled it apart, clean the CPU and cooler, new paste - an only got a week before it happened again. Maybe I should jump for a new MB and new nvme drive on that box - and maybe a faster Ryzen with a separate gpu…
I’m actually waiting a bit because there are some new AMD Ryzens coming. I’m thinking of the Ryzen 4700G maybe. It will have the graphics on it and is 8 core 16 thread.
Edit: They are also refreshing the XT lline so my current Ryzen 7 3800X will be a new on 3800XT and will have higher core and better overclocking also. Then there are others in that XT series also. Plus the 4000 Series CPU’s
What are you going to do differently then?
We’re kinda hijacking this thread! Anyway - just skip having separate /home - only a few distros - EndeavourOS, Arch and Xubuntu and maybe a Gnome - and enjoy the speed of the new nvme drives! A faster CPU with integrate graphics might be tempting too. Now let’s not get the sky marshals in to stop the hijack!
Two comments I didn’t make at the time
Looks like you got it figured out just fine.
It also looks like you didn’t find the “take a screenshot” key! F10 doesn’t always work though…, but when it does you get a .bmp file in the top level of the ESP (/boot/efi on most EndaevourOS)
Actually i had forgotten about it but you’re right sometimes it doesn’t work. I never had any issues with Deepin 15 but then V20 was not working at all. But now it’s okay since i figured out that trick of turning on the windows effects. It’s totally the opposite as i have to turn window effects off on cinnamon.
Edit: The F10 is working but how do you copy the file from the folder as i tried using sudo thunar as root and when i copy the file and paste it into a folder it is locked when i go to the folder.
You might need an AMD threadripper!
I use the Thunar ‘open folder as root’ option, and copy the bmp to ~/Pictures dir - then convert it to something more useful. Do you have a bunch of things like that option in your Thunar? It makes life much easier 
I can’t even imagine a workload that would begin to justify it for me. I’d have to do a LOT more compiling for starters!
That’s why I have been playing around with ARM devices. They have become powerful enough to do most anything you want to do that isn’t CPU intensive. The payoff, the Odroid N2 handles a full blown EndeavourOS with Gnome and does a great job of it for 3 watts idle to 4 watts under usage as read on the Kill-A-Watt meter at the wall outlet. My Ryzen 7 2700 rig pulls 30 watts at idle and goes up to 60 watts under load. I should get Prime95 that runs the CPUs at 100% and see what it pulls. I am more and more using the Odroid for daily stuff such as E-mail, spending time here and other forums, Gimp, and etc, then fire up the Ryzen if I want to run HandBrake, or any serious gaming, which I don’t user either very often any more.
