>>1250006Hello anon, I want to give an update and have another question, if you don't mind.
The Linux SSD still works and can be accessed from another system. Everything was there. Now, about that EPS thing...
My Windows SSD looks a bit like your screenshot, with a 500 MB EFI Sytem Partition.
The Linux SSD had a partition called Boot/EPS. Does that mean I had one too many?
For now, I've wiped the Linux drive and will start fresh. If those two partitions were the problem, how can I avoid it the next time? I had the Windows drive plugged in, active and present during the time I installed Linux. I wanted to have GRUB with both Linux and Windows selectable. That worked for a couple of start-ups, until it didn't any more. Something I did wrong during the install?
Thanks for all your help.
