Which EFI file gets to boot and which one gets the boot? I've attached a screenshot of the partitions as they are now, but I'm not sure where to go from here. Even if it's a wash, I'm concerned something happened with the partitions that would make a 'clean' reinstall a disaster. I'm a complete newbie in over my head and quite frankly am wondering if it's even possible to fix at this point. There are only two boot options this time around,Īnd this time switching the boot order didn't have an effect. Ran a grub recovery tool, and when the system restarted it only wants to boot Windows again. Switched generic #2 to load first and that did load into Zorin, but. Windows Boot Manager (HFS256G39TND-N210A).That also kind of worked, in that there were now three boot options in BIOS: I followed the advice here: partition - Zorin/Windows 7 Dual Boot on New Hard Drive, no GRUB! - Unix & Linux Stack Exchange (in short, remade the bootstick, created a mountpoint, mounted system on mountpoint, change root, reboot)

The computer automatically booted into Windows. Got it switched back, but at that point, Zorin seemed gone. The upgrade itself went fine, but things went wrong when I tried to reinstall a driver and instead of disabling secure boot switched from UEFI to Legacy BIOS boot mode. I recently upgraded from Zorin Core 12 (yes, I know) to Core 16 as a dual-boot with Windows 10.
