Hi everyone.
I had a Mojave Clover installation that worked very well for the past 6 months, so I though it was the time to update to Catalina.
I have Mojave on a Sabrent 1TB NVMe and yesterday I made a fresh Catalina Installation to a spare 250gb Samsung 850 Evo. Let call them SSD Mojave and SSD Catalina.
I followed the Catalina Mini guide and everything worked fine, I successfully boot on Clover, Installed Catalina and boot on the new Mac OS. Catalina is working just fine - from what I can tell.
Now going back to the Mojave installation, It seems like something is messing up with the Mojave Clover boot.
1st:
Although I have set up the Default boot Volume as Mojave SSD in clover, the first drive that shows when I boot is the Catalina one (So I have to manually switch to the Mojave SSD during clover boot, and it doest boot in Mojave properly.)

2nd:
If I disconnect the Catalina SSD (so apparently the situation is exactly the same before the Catalina new installation and it should work perfectly as before), I cannot boot anymore on Mojave. I get this error after clover boot.

If I connect the Catalina SSD drive, I can still boot on Mojave
(From the Bios boot after pressing F12, I always select the Mojave SSD drive - No the Catalina one).
I did some research and it could be something related to NVRam but I'm not sure, I didn't find the proper answer yet.
Also, this is not the first time that this happen to me.
A few months ago I tried the same process with a OpenCore Catalina installation and I had a similar situation where I could boot from the new Clover Catalina but I couldn't boot anymore on the previous volumes.
After a few hours of panic because I had 2 different backup drivers of Mojave (so I thought I was safe before start everything) and none of them was booting.
I figured out a way to boot on Mojave (not sure how) and so I decided to delete the new OpenCore installation and don't update to Catalina.
There is definitively something wrong I do that mess up with the clover boot but I'm not sure what.
Any of you have any idea? Any way to avoid all of this and have all the volumes booting properly?
Ps.
Although I have been running hackintosh for 7-8 yeas now I'm not an expert and I'm sorry if what I'm asking is something very simple that I shouldn't ask. I thank you in advance if you find the time to help me on that.
