After a few months since my last attempt, I downloaded a new ISO and tried again to install Endeavour OS. The installation went smoothly, I rebooted and did updates, so far so good.
Then I installed Zorin OS Lite 15 on another partition, to make it easier to reconfigure my Grub. Everything worked well. I rebooted and all seemed well.
The next time I attempted to boot to Endeavour (and every time since), I make the selection and get a black screen. No cursor, no nothing. I’ve tried adding nomodeset to the boot sequence, to no avail. All my other distros boot just fine.
I’m on a System76 Galago Pro 2 with an i5 processor, 16 Gb of RAM, a 1 Tb spinning metal drive and a 250 Gb M.2 SSD. I have 4 distros on the spinning disk, and 3 on the SSD, with Endeavour on the SSD. Boot sector and Swap sector are also on the SSD.
Any ideas? I’d hate to try reinstalling again. I am not feeling tied to this distro, so I may not have it on my system long while waiting for the response, but I’ll keep it on for at least a few more days.
The way it tends to work is that the latest installation controls the Grub. So I try to use a distro which has Grub Customizer in the repo or can be added via a PPA. In this case, I was going to do two installations, so I did Endeavour first and then Zorin Lite.
That is the question, and those of us who distrohop should not be judged. I am co-host of the Distrohoppers’ Digest podcast. If you don’t want to do that, fine with me, but if I do, I don’t need to be asked this question.
I run lots of distros, on this machine 7 at one time. The only time this has happened is with Endeavour. Also, you can look at another post I made as to what happens with me when I use Grub Customizer with Endeavour OS as the owner of Grub. It wasn’t pretty.
I keep hearing good things about this distro. I’m hoping I’m just finding bugs nobody else noticed because nobody else is me. And I haven’t been treated rudely, just not been given answers I could use.
I will try one more install and then, if nothing changes for the better, leave it alone for another 6 months.
OK, then I guess the booting has been messed up when installing Zorin.
As you suggested, booting with the EndeavourOS USB stick, arch-chrooting to the installed system, and fixing the boot should help.
