Seems to be a common problem and I thought I had fixed it except for one speedbump. Also I can't boot into any OS right now, the window's bootloader is messed up now as well. So I'm stuck in limbo and would like any help at all.
boot-repair and had a separate boot/efi at the beginning of my sda. I have two ssd's, the internal ssd and an actual ssd. I'm trying to install everything on the issd (
sdb) and only put the bootloader/grub whatever needs to be on
I got this message:
Boot successfully repaired.
You can now reboot your computer.
Please do not forget to make your BIOS boot on sda3/EFI/ubuntu/grubx64.efi file!
But I don't see an option in my bios to boot specifically to that. I think if I could, everything would be fine.
Here's my boot-repair log as well - Boot-Repair Log.
