Yah it’s me again, second time I install with Pop OS on same drive, use existing boot/EFI partition (no format) = both OS will not start (pop = no login/grey, EnD=black, no response to alt-crtl-f-this).
On positive side, I now have a full up EnDOS install on my daily desktop (too afraid on hybrid NV laptop tho, waiting next ISO). What on earth could be going on with EFI partition to kill both OS dead??
At this point IDC, I’m full on Endevour, just passing along this oddity
(yep, I also donated :-)) Love, D3v
An unqualified guess: Could it be due to the fact that that Pop OS uses systemd-boot and writes the kernel images to ESP? Did you use Grub in your EnOS?
