Installtion Issue
Axios yep it's happened to me with linux and windows. Solus get's bullied a lot in my experience, probably because efi bootloaders is alien to most things grub and also to windows who has a bootloader...although I saw a single instances here recently where someone claims Solus wrecked all their other existing boots but I've never seen that. Strange times!
UPDATE for my mates.
I tried two more installations and botf failed. Since Mint took a powder on me,
I decided a last attempt, with Solus 4.5 XFCE. Now the installation was NOT
a dual bootie, but a single installation on the entire HDD.
HOLEY VACA [COW] <---- Latin, it not only did it install, but bootied up as well !!!!!!!!!!!!!!!! :<))
Brent, was right about the problems with dual OSs, on a single drive. Same issue when da wifey
is driving.
The grubhub found itself on another HDD, so it required the change in HDD start up order. I bet if
I try to reinstall MInty 20 next to Solus, it will fail too.
The installer is the BEST I have ever used; quick, easy and with clear instructions. Mint installer, [21.3]
is rather AARPish and much slower. And it was not the UEFI nor the advanced kernel, which
I speculated as to the issue, in this twelve-year-old rig.
I wonder what I should do with MInt ??? There is an orphanage just three miles from me.
I used to bee Solus, until I got married.
I should add, dat Solus was installed as an EFI. None of my
other partitions have this classification. No DEI installations,
tank goodness.
Five stars to Brent on Google Map, for his suggestion, which lead
to this success !!
After three days of labor, my rig is up to par !!!! Solar installed with Mint 20 and Mint 21.
The Linux OSs welcome each other on an HDD, with operating OSs. In the meanwhile,
Mint 20 was still having issues with the network womanager; which resulted in me
breaking the OS. Too many modifications. I should add, Solus removed MicroGates7
from the bootloader. :<))
I reinstalled Mint 20 and den Mint 21, next to Solus. Then I discovered dat the Grubhub was
all messed up, as no HDD would boot. Oh dear, what have I done or undone ? The nightmare
was going to continue into a daymare. I call my old friend, Ronny Rescatux, whom said he
would arrive shortly, after break-fast. The first attempt failed, I lamented. Rescatux moved
to the second option, which should have been the first; perhaps it was the excess maple syrup
on his bits ?
I held my breath, as the rig bootied. Holey vaca, there it was, ALL THE BOOT OPTIONS !!!!!

I now have four Linux OSs and one MicroGates 7, on three HDDs. This was quite an experience [experepain?].
I did add to my knowledge base, despite the fact that my wife [wifi], was screaming at me to leave
the Linux bunker or she would give me Das Boot.! I assured her I would, after one more frontal attack.
PS: No HDD(s) were disconnected during this medical tech procedure.
**that you worked so hard to get Solus running, and succeed, just to purposefully sabotage yourself again and foul it up with a grub distro is so Linux Spirit Award 
.I try to do this once a year to stay sharp.
**don't go to the trouble of orphanage, just leave Mint on the curb for the coyotes. (natural order).
**Holy Vaca. You've accepted that you will never wear the pants in the marriage arrangement, that's step 1. you could tactically avoid Das Boot by telling her that you are writing a thank you card to her mother or shopping for a gift for her online. you should get a wider berth. a friend told me this works
.

Lots of laughs, Brent!!! I'll leave Minty on the curb for the Phoenix Coyotes.
Our abode is on a sailboat, so the "winder berth" is not an option.
